Ceramic Foundry sand is made from high quality 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. Chemical and Physical Composition: Main Chemical Composition: Al2O3≥75% Fe2O3≤5% TiO2 ≤5% SiO2:5%-20% Physical

Chromite sand is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa . The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.

Specifications Feature: 1. Heated Volume Stability 2. High thermal conductivity 3. Strong alkali resistance 4. Solid phase sintering, non-sticking sand THE ADVANTAGE OF CHROMITE SAND Comparing with silica sand, chromite sand can avoid most sand stick on the casting, therefore it can also save cost to make surface treatment. Moreover, chromite can be recycle used

Ceramic sand has excellent properties, including spherical shape, high refractoriness, good crush resistance, inert chemical characteristics, high reclamation yields.
