Silica bricks
Silica bricks are made from high-quality, low-alumina quartzites. Below approx. 700 °C they are very sensitive to rapid heating and cooling because of the abrupt crystal transformation. Above 700 °C, however, they have excellent thermal shock resistance.
Typical applications
- Electric furnace roofs
- Glass furnace substructures, superstructures and crowns
- Hot blast stoves
- Coke ovens
Grades on request
For silica bricks, we will be happy to recommend suitable grades and their technical data in person – matched to your operating temperature and application.
