The hot repair expansion rate of the kiln is almost zero. Zero expansion silica brick

The material of silicon brick is quartzite with a small amount of mineralizer. Its mineral composition is tridymite, cristobalite and glassy structure formed at high temperature, and its AiO2 content is above 93%. Among the well-fired silica bricks, the content of tridymite is the highest, accounting for 50% ~ 80%; Followed by Shi Ying, accounting for only 10% ~ 30%; The content of Shi Ying and glass phase fluctuates from 5% to 15%.

Main advantages of silicon:

1. High softening temperature under load. High-quality silicon brick can reach 1705℃, and ordinary silicon brick can reach 1630℃.

2. Good thermal shock resistance at high temperature. The volume of silicon brick will hardly change above 700℃, so the temperature fluctuation above 700℃ will not damage the silicon brick.

3, the components are easy to melt and diffuse in the glass, and the pollution to the glass liquid is small.

4. Simple manufacturing.

5. Good economy.
