- Ferric Oxide, Crystalline (Fe2O3) Formula:
Fe2O3
A purified, naturally occurring mineral called specular hematite (Fe2O3). It a blocky, heavy iron-based crystal and the most stable form of ferric oxide in a fully crystalline state. The product will not rust or oxidize as its crystalline composition makes it a stable form of ferric oxide (Fe2O3). No rust means it will not stain or clog metering valves. It is non-hygroscopic and will not absorb moisture. It is non-magnetic and will not stick to steel due to magnetic attraction, but it has a very weak susceptibility to magnetic forces.
Composition of ore: Iron= 70%, Oxygen= 30%, and Crystalline silica= 0.5% max.
Lumps, granules, 10 x 20 mesh, 12 x 50 mesh, and various powder granulations custom size reduced down to ~ 1 micron
Meets Mil-A-21380B Type I for aluminum oxide, and Mil-A-22262B(SH) for hull abrasives.
Recycles 3-6 times using conventional air-wash systems. Additional grit (approx.25%) must be added to the system to supplement degradation loss after each recycle.
