1.Ceramic foundry sand is Solid sphere: The shape of Ceramsite is spherical with a smooth surface and less surface area and offering a very good flowability and filling ability. To compare with other sands else, less binder is used at the same mold strength and higher venting ability. It also offers excellent collapsibility.
2.Ceramic foundry sand with Lower thermal expansion rate: It makes the dimensions of castings better, less crack and defect, and higher output.
3.Ceramic foundry sand with Lower breakage rate: Ceramsite has a higher density and a very lower breakage rate at the reclamation. It makes a better reclamations rate to reduce the waste sand and the pollution.
4.Ceramic foundry sand has High refractoriness: The major chemistry is Al2O3 and SiO2, so mostly mullite and corundum phase in the Ceramsite will make sure high refractoriness and thermal stability. And PH Value appears neutral. It is suitable for all kinds of metal and alloy castings.
