Chamotte mass is made from fired clay containing large amounts of aluminum oxide (Al₂O₃), silicon dioxide (SiO₂) and smaller amounts of other minerals such as iron oxide (Fe₂O₃) or alkali silicates. The manufacturing process involves high-temperature firing at temperatures above 1400 °C, which ensures the creation of a hard and durable material.

The highly effective fine-grained casting chamotte mass AWL D 0-1 is intended for use in steel foundries for the creation of casting channels, casting pipes and fittings. The initial moisture content of the material upon delivery is approximately 8%. Before use, the material is simply moistened, pressed into the desired shape and fired. Its unique properties guarantee significant abrasion resistance, heat resistance and low shrinkage. Even during demanding and precise casting at high temperatures, the material does not release into the melt.
