About scandium metal

Types of Scandium Metal

Based on the product and its parts, there are numerous types of Scandium metal like alloying elements, rare alloying metal, and so forth. The types are discussed below.

Alloying elements

The most crucial application of Scandium is in aluminium alloys. Small Scandium additions significantly enhance the strength and toughness of these alloys. At the same time, Scandium forms a solid alpha aluminium-scandium phase that inhibits grain growth during heat treatment. This leads to improved mechanical properties like tensile strength and fatigue resistance. Such features make the metal alloy appealing for high-performance construction in the aerospace and automotive industries.

Rare alloying metal

Scandium is still used in titanium alloys, which are discovered in aerospace, medical implants, and chemical process components. Scandium enhances titanium's strength while maintaining its lightweight properties. Also, it improves the alloy’s resistance to deformation at higher temperatures. This makes it a practical choice for components in specialised engineering applications where heat and stress are often problematic.

High-intensity discharge lamps

Scandium can still be found in metal halide lamps, especially high-pressure sodium lamps for industrial and commercial lighting. Scandium works with other halides to produce a bright, efficient white light. That is better than yellow hues from sodium street lamps.

Lasers

When combined with other materials, Scandium produces, for example, a laser employed in solid-state laser technology. This laser is especially useful in precise welding or cutting, medical procedures, and even laser cleaning.

Hydrogen storage

Scandium can still be used in metal hydrides. In a hydride, Scandium and other metals form compact storage and transportation systems for hydrogen. This application is growing relevant in developing fuel cell technology and hydrogen energy systems.

Characteristics of Scandium Metal

Scandium metal has distinct features that make it appealing for various uses. For example, it has mechanical, thermal, electrical, and optical properties.

Chemical properties

Scandium is highly reactive. It reacts with moisture and oxygen and forms, for instance, a thin oxide coating on its surface. This layer limits further oxidation and protects the metal. This oxidation layer, however, doesn't form in a non-oxidising environment. Scandium can still be extracted from ores using aluminium through a thermochemical reduction technique known as aluminothermy.

Physical properties

Scandium has a uniform silvery-white outlook, with a soft texture that can be scraped with a nail. The metal has a density of around 2.985 grams per cubic centimetre. This density makes it moderately lightweight compared to other transition metals.

Although poorly conductive, Scandium still has good electrical conductivity. This property comes in handy to offer thermal conductivity, which aids in heat dissipation in various electronic and engineering applications.

Scandium has a modest melting point of 1541 degrees Celsius. This makes it stable at elevated temperatures. All these features facilitate the metal's broad use in various innovative industrial and technological applications.

Mechanical properties

Although pure Scandium metal is relatively soft, it possesses high tensile strength when alloyed with other metals. Scandium, for instance, improves the mechanical properties of aluminium alloys by strengthening them without adding weight.

Uses of Scandium Metal

Scandium metal is a basic element employed in alloy studies and manufacturing to improve alloy strength and stabilize other compounds. The following are common uses of Scandium metal, including its alloys and other uses.

Aerospace and automotive industries

Adding Scandium enhances aluminium-lithium alloys used in airplane frames, fuel tanks, and body panels. These alloys reduce weight without losing tensile strength and corrosion resistance.

Furthermore, the auto industry employs Scandium-enhanced alloys for building components used in racing cars and high-end vehicles. In these vehicles, weight reduction and increased strength are critical for performance and durability.

Ceramics

Scandium oxide is still used in yttria-stabilised zirconia ceramics. These ceramics have high toughness and strength, making them ideal for dental and industrial components.

Coatings

Scandium is added to titanium coatings to improve their wear and corrosion resistance. This application is specifically useful in the aerospace industry, where durability is vital.

Batteries

Nickel-SM alloy has better hydrogen absorption properties. This property enables it to be used in nickel-metal hydride batteries found in electric vehicles. This helps provide energy without the battery pack being bulky.

Ion glasses

Scandium is used in ion-conducting glasses for solid oxide fuel cells. This Scandium metal application helps enhance ionic conductivity. This makes it effective in energy conversion and storage applications, like fuel cell technology. Fuel cells convert hydrogen and oxygen into electricity, so efficiency becomes critical.

Sports equipment

Scandium improves the strength-to-weight ratio of titanium alloys. This is commonly used in premium sporting goods like bike frames, baseball bats, and fishing rods. The Scandium addition improves performance by making the equipment lighter and more durable without compromising toughness.

Lasers

Scandium is mixed with other elements to produce a crystal that generates an efficient wavelength in solid-state lasers. These lasers are handy in various applications, including cutting and medical surgery. The Scandium content ensures the laser maintains consistent output and efficacy.

How to Choose Scandium Metal

When purchasing Scandium metal, several factors have to be considered to ensure the right choice is made. Buyers should consider the type of the metal, form, quality, and supplier reputation, among other factors. The following are factors business owners should consider when buying Scandium metal.

Scandium is found in different purities. The purity normally ranges from 99% to 99.9% and the above. Pure Scandium will be more applicable in the aerospace and defence industries, while lower purities may suffice for less critical uses.

Buyers should also consider the metal's condition. Scandium can still be found in powder, solid, or bulk forms. Each form has a different application. The metal in the form of powder may be ideal for buyers who want to use or sell it for 3D printing. On the other hand, bulk Scandium is more appropriate for buyers who need it to manufacture alloys.

Although Scandium is known to be a rare Earth, numerous suppliers on Alibaba.com sell the product. The manufacturers normally source the metal from ores like euxenite, tills, and pure deposits.

Buyers should also consider the metal's consistency and look for any measure certifications like ISO. Also, consider the minimum order requirement, delivery time, and payment options. These are all essential factors when choosing a supplier.

Scandium can still be used in combination with other elements like titanium, zirconium, and lithium. The combination improves the alloy's mechanical properties. At the same time, it reduces the risk of oxidation. When buying Scandium, one needs to know how much to combine with other metals for the ideal results.

Q & A

Q1. What industries still utilise Scandium?

A1. Scandium finds its use across many industries, including aerospace and automotive, electronics, medical and defence engineering structures, and even sporting goods.
