Bauxite Sintered

Description

This product is a hard and unyielding abrasive, available in spherical shapes. Starball is made by sintering fine Bauxite ore.  Bauxite is the main ore used to produce Aluminium and consists of 75% of Aluminium Oxide.

Application

Often used as to replace brown fused aluminium oxide, it can be used with conventional abrasive blasting equipment air-compressed pressure and suction jet-blasting equipment.   Sintered bauxite is also used for the following applications:  antiskid flooring, carving, etching, finishing, grinding, lapping, polishing, rock tumbling, lapidary, sandblasting, slurry mixes, surface preparation and tumbling.

Advantages

Exceptionally well-suited for use with air-compressed jet-blasting equipment, both pressure and suction.
