Our Spinel Products come from detonations of CDP formulations containing varying amounts of elemental magnesium, aluminum and dry ice.
Description: Grey abrasive powders
Composition: Approximately 95% oxides and the balance is carbon in various phases, including diamond. Some compounds are ferromagnetic. Here is a breakdown of the oxide phase according to CDP formulation:
