YANNUO CERAMIC SAND
Ceramic Sand
Introduction
Ceramic foundry sand is made from fine bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc. It is also widely used in fracturing of gas and oil wells as ceramic proppant.
Main Features
Good durability
Precision casting
Low thermal expansion
