Quality silica bricks

Quality Silica bricks are the key refractories for high temperature area of industrial kilns and furnaces including coke oven, hot blast stove, glass tank etc.
Our high quality silica bricks enjoy the main characteristic of high dense( good for thermal conductivity),high RUL and high tridymite content, low true density, low expansion, low creep and low residual quartz, accurate size tolerance, purity colors and luster forming good appearance.

1．Physical and Chemical Properties

High purity	SiO2 95-96.5%
Dense：Apparent porosity：	17-21%
High RUL	T11670-1700℃
High tridymite content	about 75%
Low true density	2.33-2.3g/cm3
Low thermal expansion	＜1.25%（room-1000℃）
（0.2MPa ×1550℃×50h）Low creep	＜0.5%
Low residual quartz：	0-0.5%

2．Technical features

Crystal silica is used as starting material, composite mineralizer and nanometer materials are used, scientific sintering and controlling schedule are adopted.

3．With dense and smooth appearance, uniform corner and edge, pure color and luster and accurate size.

4．Products quality

Developed according to Japan national scientific research item,the high quality silica bricks for super coke oven （SCOPE 21 silica bricks）passed Technical Evaluation.
