Ceramsite, also called as NFS CERAMSITE-Nice Foundry Sand, is kind of man-made spherical shape ceramic particles featured by high refractoriness, low thermal expansion made by spraying melted from the fused bauxite. It provides a simple and efficient way in the foundry industry to improving the quality of the castings, reducing the production cost and avoiding environmental pollution so it is much better than silica sand. And it is also good substitution to Chromite sand and Zircon sand because of its lower price. At the present, Ceramsite is acknowledged in the worldwide as the newest and the best ideal sand for the foundries and has a very wide feasibility of applications for the future development.

5. Ceramic Foundry Sand Characteristics
1. Low thermal expansion coefficient
2. High strength with good compressive strength and bending resistance ability and low broke rate.
3. Spherical shape, good flowability, easy to shakeout
4. Smooth surface, compact structure
5. Chemically neutral material
6. high-temperature resistance, good refractoriness
7. Recycle up to 10 times, highly cost-effective.
8. Save resin consumption with casting tech such as shell molding, Resin coated sand casting, Vacuum casting, etc.
