Buy good quality Fused silica bricks high purity at Wedge India. Fused silica bricks are a type of refractory material made from high-purity silica. They are manufactured by melting pure silica and forming it into bricks, which are then cooled slowly to form a crystalline structure. These bricks have several important properties and applications:
Properties:
1. High Thermal Stability: Fused silica bricks can withstand very high temperatures without deforming or breaking down, making them suitable for use in high-temperature environments.
2. Low Thermal Expansion: They have a low coefficient of thermal expansion, which means they resist cracking or spalling when exposed to rapid temperature changes.
3. Chemical Resistance: Fused silica is resistant to most acids and chemical reactions, making these bricks ideal for use in environments where they might be exposed to corrosive substances.
4. High Purity: > 99% SiO2 They are made from very pure silica, which contributes to their excellent thermal and chemical properties.
5. Low Thermal Conductivity: Fused silica bricks have low thermal conductivity, which makes them effective insulators.
Applications:
1. Glass Industry: Used in the construction of glass melting furnaces due to their ability to withstand high temperatures and corrosive glass melts.
2. Foundry Industry: Employed in foundries as linings for furnaces and as molds for casting metals due to their high thermal stability and resistance to thermal shock.
3. Chemical Processing: Used in the linings of chemical reactors and other equipment where resistance to acids and other corrosive chemicals is required.
4. Ceramics Industry: Utilized in kilns and furnaces for firing ceramics, where high temperatures and thermal shock resistance are essential.
5. Solar Energy Applications: Used in solar furnaces and other high-temperature applications related to solar energy.
