Product Detail:
Foundry Ceramsite, is good artificial spherical grain shape, also called fused ceramic sand. Its main content is aluminum oxide and Silicon oxide, much better properties than t silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

Advantage
Green Sand. SAFE to environment compared with silica (silicosis) and zircon sand
High refractoriness (＞1800°C)，can be used for casting various materials. There is also no need to use different sand type according to material.
High reclamation rate. Both Thermal and mechanical reclamation. Offers longer work life and reduction of sand usage.
High collapsibility. Sintered Ceramic sand spherical shape compared with angular shaped grains allows for easier separation from cast parts and improved collapsibility resulting in lower scrap and casting efficiency.
Excellent fluidity and filling efficiency owing to being spherical.
Lower Thermal expansion and Thermal Conductivity. Casting dimensions are more accurate and lower conductivity provides better mold performance.
