Ceramic molding sand is a silica free foundry sand

Ceramic Foundry sand ,also called as Fused Ceramic Sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.At the present, Ceramsite is acknowledged in the worldwide as the newest and the best ideal sand for the foundries and has a very wide feasibility of applications for the future development.

Features:

· Stable grain size distribution and air permeability

· Stable component composition

· High refractoriness (1800°C)

· High resistance to wear, crush, and thermal shock

· Little thermal expansion

· Excellent fluidity and filling efficiency because of being spherical

· Highest reclamation rate in the sand loop system
