Product Detail: Ceramic beads spherical sand is made of mullite crystals and fired at a high temperature. It is an artificial foundry sand that is regarded as the right substitute for cerabeads, chromite sand, zircon sand, fused silica sand, and even silica sand. It can obviously reduce the binder addition for resin coated sand and self-hardening sand.
