Ceramsite sand is an artificial spherical casting sand developed by SHXK, same with Japanese Cerabeads. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (at least 30% reduction in binder content), and particles high strength, non-breaking and other excellent characteristics, suitable for all types of sand foundry, especially for the coated sand. There are more successful application cases.
