Borosilicate glass

• Low Expansion Borosilicate Glass

  This glass has a low coefficient of thermal expansion. It means it does not change size much when heated. It can withstand high temperatures and thermal shock. It is used in items that are heated a lot, like furnace tubes.

• Low Alkali Borosilicate Glass

  This glass is less reactive with acids and bases than normal glass. It is used in chemical containers and valves because it does not react with chemicals.

• High Strain Point Borosilicate Glass

  This glass can take a lot of stress before it breaks. It is stronger than other glasses. It is used in places where glass might break from stress, like in outdoor signs.

• Lead-free Borosilicate Glass

  This glass does not have lead, making it safer to use. Lead is a harmful substance. Lead-free glass is used in food and drink containers because it is safer for people. It can also be used in X-ray machines because it does not interfere with X-rays.

Design of borosilicate glass

• Thermal resistance:

  This glass can withstand high temperatures and sudden temperature changes. For example, if a pot made of this glass is heated on one side and cooled on the other side, it will not crack or break.

• Chemical resistance:

  This glass is not easily affected by chemicals. For example, if a chemical spill occurs, the glass will not react or change its properties.

• Transparency:

  This glass is clear and see-through, like regular glass. It allows people to see through it and check the contents inside. This property is useful for laboratory equipment and food containers.

• Mechanical strength:

  This glass is stronger and more durable than regular glass. It is less likely to break or get damaged. This strength allows it to be used for various applications, such as making car windows or smartphone screens.

• Thermal expansion:

  This glass has a low thermal expansion coefficient. It means that when the glass is heated, it does not expand or change size. This property helps maintain the glass's shape and prevents it from cracking or breaking due to heat.

• Electrical insulation:

  This glass does not conduct electricity. It can be used in electrical applications to prevent the glass from carrying an electric current. For example, it can be used to insulate wires or protect electrical components.

• UV radiation resistance:

  This glass can block UV rays from the sun. It can protect against harmful UV radiation. For example, it can be used to cover paintings or photographs in museums.
