Ceramic foundry sand is an advanced alternative to conventional quartz sand used in the foundry industry. It is made from sintered bauxite with an aluminum content of 65-90%. The material is processed through various methods such as melting, blowing, sieving and mixing to achieve high performance in metal casting applications.


High refractory ceramic foundry sand has excellent thermal stability and a refractoriness of over 1800°C, making it ideal for high temperature casting processes. Its spherical shape ensures good flowability and uniform filling in the mold. The sand is mainly used in applications such as shell mold casting, precision casting and resin bonded sand casting.


Ceramic foundry sand has excellent thermal conductivity and low thermal expansion, which helps improve the precision and quality of the casting process. The consistency of its chemical and physical properties ensures stable performance in various casting techniques such as investment casting and vacuum casting.


Ceramic foundry sand is widely used for heavy steel castings and industries that require high-quality, durable molds. It is particularly beneficial for casting complex metal parts, with excellent surface finish and high mold strength.
