This compound is highly soluble in water and forms a viscous solution. Upon complete ionization, the solution is capable of conducting electric current. This compound finds its usage mainly in glass etching and insecticides. It is also used in cement and concrete industries to enhance their physical properties and chemical resistance.
Water Solubility
Sodium silicofluoride is highly soluble in water. This means it can dissolve easily in the water medium. Once it is soluble, it forms an acidic solution that contains fluoride ions, silicic acid, and sodium ions.
Crystalline Structure
Sodium Silicofluoride normally appears as a colorless crystal or white powder in a typical laboratory environment. The actual crystalline structure of sodium silicofluoride depends on factors such as temperature, humidity, and concentration of the solution.
Acidic Nature
When dissolved in water, sodium silicofluoride dissociates and forms an acidic solution. This acidic solution can enhance the solubility of metal ions and also improve the activity of certain catalysts. This makes it therefore useful in industrial applications.
Ionic Composition
The Sodium silicofluoride formulation consists of sodium ions, fluoride ions, and silicic acid anions. These components make the compound useful in various chemical reactions. Usually, the ions can be used to carry electric current in solutions, giving them electrolytic properties that make them perfect for certain industrial uses.
Water Treatment
The chemical compound sodium silicofluoride is commonly used in water treatment processes for water fluoridation. The purpose of water fluoridation is to improve dental health. This is because sodium silicofluoride helps to release controlled quantities of fluoride ions into the treated water.
The water is then automatically supplied to the community, where the fluoride ions get integrated into dental construction by decreasing dental caries incidence. Besides this, some of the compound's fluorine content is also recovered and used for recycling and producing aluminum fertilizers and pesticides.
Metallurgy and Aluminum Production
Sodium silicofluoride is also widely used in the production of aluminum and other metal refining and smelting processes. In these applications, this compound serves as a flux that enables the removal of impurities from molten metal.
In the process, sodium silicofluoride reacts with impurities to form slag, which is then removed from the ore to obtain purified aluminum. This is the reason why suppliers of aluminum ores provide buyers with this chemical compound.
Glass and Ceramics Industry
The sodium silicofluoride is mainly used in the glass and ceramics industry to improve the properties of finished products. In particular, sodium silicofluoride is added to glass formulation to lower the melting point and improve the chemical resistance of the produced glass.
Thus, glass manufactured with sodium silicofluoride is more durable and less susceptible to corrosion when exposed to moisture and other chemicals.
Agricultural Uses
Sodium silicofluoride is also used in agriculture, particularly in pesticide manufacturing. This is because it acts as a carrier in pesticide formulation, enabling even distribution of active ingredients. Some of its active ingredients include sodium fluoride and silicon dioxide, which are effective against a wide range of agricultural pests.
Safety Precautions and Handling Guidelines
Sodium silicofluoride is considered hazardous and should always be handled with the correct personal protective equipment (PPE). Sodium fluoride contained in this compound is highly toxic to living organisms. Also, the compound is an irritant, and therefore skin contact should also be avoided.
Because it is toxic, it should also not be inhaled, and dust formation should be controlled. It is recommended for users to always check the safety data sheet (SDS) for detailed information on first aid, toxicity, handling, and disposal recommendations.
There are a lot of factors that influence the purity, quality, and quantity of sodium silicofluoride. These factors include the source of raw materials, the extraction methods, and the geographical location of the mining areas.
Purity and Composition
This product often comes in varying grades, depending on the intended application. Industrial-grade sodium silicofluoride typically has lower purity (around 90-95%) compared to pharmaceutical or food-grade, which may exceed 99% purity. Common impurities include calcium fluoride, iron oxide, and aluminum compounds.
Packaging and Storage
Sodium silicofluoride is usually packaged in 25kg or 50kg bags, drums, or bulk containers. For industrial purposes, the chemical can be supplied in bulk for large-scale operations.
The product is usually always recommended to be stored in a dry, cool, and well-ventilated area away from incompatible materials, such as strong acids or ammonium compounds. Moreover, it should be kept in tightly sealed containers to avoid moisture infiltration, which may cause caking and loss of chemical reactivity.
Supply and Demand Dynamics
The demand for sodium silicofluoride mainly depends on the health of industries like water treatment, aluminum production, agriculture, and glass manufacturing. Often, the supply comes from both domestic production and importation. This is especially the case when there is a shortage in the market or the product is in high demand.
Quality Control
To ensure safe handling and effective applications, sodium silicofluoride is always tested against multiple parameters, including purity, particle size, and chemical composition. These tests are often conducted across third-party laboratories to guarantee neutrality.
Define the Intended Use
This is to say that buyers and users should first identify the specific application they will use sodium silicofluoride for. The specific applications can be in glass etching, water treatment, pesticide manufacture, or aluminum processing. Often, for specialized uses, it is ideal to get purified or industry-specific grades of the compound.
Assess Purity and Quality
At this stage, it is important for the users to make sure that the sodium fluosilicate they are getting has the right purity level for the intended use. In manufacturing and industrial processes, users may require low-grade compounds that are over 99% pure.
Conversely, pharmaceutical and food industries often require high-grade purification of the compound to reduce the risk of contamination and adverse reactions. Buyers should also pay attention to quality by ensuring that the product is sourced from a reputable manufacturer or supplier to ensure consistency and quality.
Evaluate Packaging and Storage Solutions
Users should consider the packaging of sodium fluorosilicate that is suitable for them. Such packaging should be in resealable containers, or they may opt for bulk quantities. This is especially so if they are in large-scale operations.
Again, businesses looking for bulk supplies should also verify the supplier's ability to provide in bulk or offer customizable packaging solutions to suit end-user needs. Additionally, it is important to ensure that the supplier has the correct storage and handling practices to maintain product integrity due to the compound's sensitivity to moisture and environmental conditions.
Review Safety and Handling Procedures
It is always important for users to review safety precautions and handling guidelines. This means they should ensure they have proper personal protective equipment (PPE) in place. Meanwhile, they still need to check the product's safety data sheet (SDS) for detailed information on first aid, first responders, handling, and disposal procedures.
Compare Pricing and Availability
Buyers normally need to get competitive pricing, but they also have to ensure that quality and reliability come first. They should get multiple quotations from different suppliers, taking into account factors like MOQ, lead time, and cost of shipping. Suppliers' reputations and reviews can also be compared to ensure that the users only deal with reliable suppliers who deliver quality products on time.
Sodium silicofluoride can also be called sodium fluosilicate. The two terms are often used interchangeably to refer to the same chemical compound.
Sodium silicofluoride comprises three main chemical components. They are sodium, fluoride, and silicon ions. These ions are obtained from a reaction between sodium fluoride and sulfuric acid.
Users normally store sodium silicofluoride in a dry and cool environment. It is also stored in a well-ventilated area that is free of exposure to incompatible materials such as strong acids or ammonia.
Sodium silicofluoride is considered hazardous. All people handling it should have the recommended personal protective equipment (PPE). They should also avoid all direct contact and inhalation because it is toxic and an irritant to living organisms.
During a sodium silicofluoride spill, all affected persons should wear appropriate PPE. They should all work together to control the spill by using suitable absorbents and ensuring that all contaminated materials are securely placed in proper hazardous waste containers.
