Microgrit PXA Series
Unfused Aluminum Oxide Powders
Microgrit PXA powders are designed for the use in the manufacturing of polishing and buffing compositions, tumbling creams and lapping compounds. They can also be used both wet and dry tumbling operations and for finish work on metallographic and crystallographic specimens. They are prepared in ceramic lined equipment to eliminate metal contamination and are uniformly white in color. Particle size and absorptive properties are controlled within very close limits.
MICROGRIT PXA powders vary by particle size and absorption rates.
