Inorganic Abrasives

Tripoli powder is a rose or cream-colored, free-flowing non-metallic odorless powder insoluble in water. Tripoli, whose chemical name is silicon dioxide, is a highly porous lightweight material that can easily be cut with a fingernail and crumbled into a fine powder between the fingertips; however, the individual grains (usually 0.01 millimeters or more refined) are so strong they will scratch steel.

Bauxite is a rock with high aluminum content. Bauxite is a generic name for deposits composed of one or more hydrated aluminum oxide mineral species. Bauxite contains many impurities, such as silica, iron and titanium oxides, and other elements, mostly in minor or trace amounts. There are four basic grades of bauxite- Chemical grade- (55-58% min. pure), Abrasive grade- (55% min. pure), Refractory grade- (59-61% min. pure), and Metallurgical grade- (50-55% min. pure). Bauxites are typically classified according to their intended commercial application: metallurgical, abrasive, cement, chemical and refractory.

Purities available from 98% (industrial grade) to 99.999% (high purity grade)

Burundum gives you a high-density, long-wearing, non-contaminating industrial grinding media that resists chemical, thermal, and mechanical shock. Burundum Grinding Media is nonporous, nonconductive, and nonmagnetic, making it ideal for wet or dry grinding.

Emerundum is a naturally occurring odorless mineral having its broadest use as an abrasive in polishing applications. A mixture of corundum (Aluminum Oxide) with an iron-bearing mineral and other trace impurities such as mullite, titania, silica, and magnesia.
