Zero Expansion Silica Brick Details

The Zero expansion silica bricks, also known as zero thermal expansion (ZTE) silica bricks, are a specialized type of refractory material engineered to exhibit minimal thermal expansion over a wide temperature range. These bricks are primarily composed of silica (SiO2) and other additives that help in achieving their unique properties.

Features

1. Ultra-Low Thermal Expansion:Zero expansion silica bricks possess an extremely low coefficient of thermal expansion (CTE), approaching zero over a specific temperature range.

2.High Thermal Shock Resistance:These bricks demonstrate exceptional resistance to thermal shock, making them suitable for applications where rapid temperature changes occur, such as in kilns, furnaces, and high-temperature industrial processes.

3. Chemical Stability:They have excellent chemical stability and resistance to corrosion from various chemicals, acids, and alkalis.
