1. Ceramic Foundry Sand Introduction
Our high quality Ceramisite sands are made by fusing, spraying, sieving and purifying high Alumina Calcined Bauxite. They can be used in casting all sizes of steel parts. The spherical shape produces high density material with excellent flow characteristics. The main chemical composition is Al2O3 which provides an excellent refractoriness and stability.
Ceramsite is ball-shaped, high heat-resistant, low heat dilating rate. it has advantage of cost and performance than Chromite sand and zircon sand that provide the effective ways to improve the quality of the foundry, cost-down and less damage to the environment.
