Silica M300/400/500/600/800

SILICA M Silica Flours are produced by iron-free grinding and accurate sieving by use of air-separators. A selected silica sand with a SiO2 content of over 99 % is used as raw material. The purity, controlled particle size distribution, chemical inertness, optical properties and hardness make Silica M Silica Flours the performance standard for foundry, metallurgical and investment casting applications.
