Fireclay Refractory
Fireclays are clays that are immune to deformation and melting at high temperatures in the ceramics industry. Unfired refractory bond clay and fireclays (chamotte), fired refractory clay, or similar grog ingredients are used to make fireclay refractory bricks. The basic components of fireclay refractory bricks are 18 percent to 44 percent alumina (Al2O3) and 50 percent
