Ceramic Sand

China factory supply Ceramic Foundry Sand / Foundry ceramic sand

Product Description

 Ceramic foundry Sand, 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, Ceramic sand 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.
