Chromite sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production CHEMICAL COMPOSITION Cr2O3 ≥46.0% SiO2 ≤1.0% FeO ≤26.5% CaO ≤0.3% MgO ≤10% AL2O3 ≤15.5% P ≤0.003% S ≤0.003% Cr/Fe 1.55:1
Description: Ceramsite sand is a kind of fused ceramic sand,it is made from calcined bauxite with main content aluminium oxide processed by melting,blowing,sieving and blending. Ceramsite sand Physical and Chemical Composition Chemical Analysis[%] Al2O3 70-75 SiO2 8-20 Fe2O3 ≤3 TiO2 ≤3.5 CaO ≤0.45 MgO ≤0.35 K2O ≤0.33 Na2O ≤0.08 Physical Properties Grain shape Spherical Ball Roundness
: ceramic foundry sand offers longer work life and reduction of sand usage ceramic foundry Sand’s spherical shape compared with angular shaped grains allows for easier separation from cast parts and improved collapsibility resulting in lower scrap and casting efficiency SAFE – to environment compared with silica (silicosis) Lower thermal expansion and Thermal Conductivity. Casting
Ceramic Foundry sand ,also called as Fused Ceramic 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.At the present, Ceramsite is acknowledged in the
