Premium Spherical Ceramic Sand for Casting | China Factory Suppliers
Ceramcast spherical ceramic sand is a premium, high-performance refractory material specifically engineered for high-end sand casting. Composed of a stable Mullite and Corundum mineralogical structure, it provides an exceptional thermal stability profile with a refractoriness exceeding 1800°C, ensuring superior performance in the most demanding foundry environments.
Designed to replace traditional silica sand, Ceramcast significantly reduces casting defects such as sand burn-on, sintering, and veining. Its precise spherical geometry and low angular coefficient optimize breathability and surface finish, while its exceptional recyclability—up to 98%—promotes a sustainable, dust-free, and eco-friendly green foundry operation.

Key Advantages
Extreme Refractoriness
Withstanding temperatures ≥1800℃, it eliminates sand burning-on and sintering in high-temperature casting conditions.
Dimensional Precision
A low thermal expansion coefficient drastically reduces deformation and improves the size accuracy of final cast products.
Superior Surface Finish
The spherical shape (angular coefficient <1.1) improves breathability and ensures high-precision surface accuracy.
Cost-Effective Volume
Bulk density similar to silica sand allows 25% more sand core production per weight compared to fused ceramic sand.
Universal Compatibility
A neutral material perfectly applicable to both acid and alkali resins across various casting methods.
98% Recycling Rate
High renewable characteristics reduce purchase costs and minimize solid waste for a green foundry.
