Products Description
Silica brick is made of quartz stone material, the content of SiO2 is above 93%. It has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C, RUL is beyond 1620°C.
SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk. So there is a close contact between the changes of SiO2 crystals and the produce, performance and usage of silica bricks. During the heating, there will be changes of the bulk, and cristobalite changes most, then quartz, phosphorus quartz is the slowest of all and it also has good heat-conductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.
Properties of Super Duty Silica Brick
High Purity, SiO2≥96%,
Metallurgy, building materials, chemical industry, petroleum, machinery manufacturing, silicate, power and other industries.
It’s widely used for the linings and insulating layers of industry kilns, and the areas without strong erosion and souring action by molten materials at high temperature.
