Our sands
Industrial foundries, refractory materials
Our foundry sand has a high SiO2 content, suitable granularity, and high temperature resistance, making it an excellent material for industrial foundries, sand casting, and sand cores. Our technical and micronized sand is also used in precision casting technology. It has a special place in the production of heatproof materials such as linings for thermal equipment (aggregates), coke ovens, blast furnaces (including wind heaters), glass furnaces, electrolysers for primary aluminium production, and others. It is also used to produce fireclay and silica bricks, chimney liners, refractory mortars and cements.
