Fused Silica Brick for Sale

Description

Fused silica brick is a kind of high-precision and high-purity quartz material, which is made of pure quartz sand heated to more than 1800℃ in an electric furnace and fused to a fused silica tourbillon, and then cut by a professional cutting equipment, and can be produced in various specifications and sizes.

Features

Excellent volume stability

Fused silica bricks have excellent volumetric stability, and the use of fused silica ceramic bricks for fire-resistant furnace masonry can be achieved without leaving expansion gaps.

Excellent heat resistance

Fused silica bricks can withstand extremely high temperatures, typically 1700°C (3092°F) and higher. At high temperatures, it maintains its structural integrity and shape without melting or deforming.

Low Thermal Conductivity

Fused silica tiles have very low thermal conductivity, making them an excellent insulator. In high-temperature applications, it minimizes heat transfer, reduces energy loss and increases energy efficiency.

Outstanding Thermal Shock Resistance

Fused silica brick has excellent thermal shock resistance. It can withstand sharp temperature changes without cracking or flaking, ensuring its reliability and durability in temperature fluctuating environments.

Chemically Inert

Fused silica tiles are chemically inert and highly resistant to most chemicals, acids and alkalis. This property makes them suitable for applications involving corrosive or reactive environments, thus maintaining their stability and longevity.

High mechanical strength

Fused silica bricks have good mechanical strength and are able to withstand stresses and loads. Structural integrity is maintained even when subjected to weight and stress in high temperature environments.

Transparent to infrared (IR) radiation

Fused silica tiles are extremely transparent to infrared radiation, allowing for efficient heat transfer. This property is beneficial in applications where precise control of heat distribution or infrared heating is required.

Electrical Insulation

Fused Silica Brick is an excellent electrical insulator and is therefore suitable for applications where electrical conductivity needs to be minimized.
