Ceramic foundry Sand (Ceramisite Sand) is a new kind of artificial foundry sand. It is ball-shaped, with a high heat-resistance, low heat dilating rate. Comparing to the same purpose products in foundry field, such as chromite sand and zircon sand, it is much more advantaged on cost and less damage to the environment. It is the best selection for the foundry field and has a good vision of development.
