Mullite Sand

Mullite sand, composed primarily of 3Al₂O₃·2SiO₂, is a superior refractory material renowned for its exceptional thermal stability, high melting point (≈1850°C), and low thermal expansion. Widely used in foundry, ceramic, and metallurgical industries, mullite sand offers outstanding resistance to thermal shock, chemical corrosion, and mechanical wear, making it ideal for precision casting, furnace linings, and advanced ceramics. Its unique microstructure ensures excellent volume stability at ext...
