A novel blend of alumina and diamond abrasives which has proven itself to
be an excellent polishing agent for precision optics materials such as calcium
fluoride, zinc sulfide, and zinc selenide among many others. This combination
yields excellent scratch-dig free surfaces material removal rates by selecting
the appropriate sized diamond product. Pureon has extensive experience
manufacturing multi-particle blends that exhibit synergistic properties, and
AlumaGem continues that legacy into the optics market.

AlumaGem Polishing Slurry is comprised of individual crystallites of nanometer
sized phase alumina in precise proportion with discreetly sized fine diamond
powder. A pH of 8.5 is maintained for maximum performance.

The presence of the alumina material also permits effective recirculation of
AlumaGem.

Highlights
– Tightly distributed and controlled diamond alumina abrasives
– Industry-leading suspension chemistry will remain stable for six months with no agitation
– Dilutable to tune process to desired friction level and removal rate controlled diamond abrasives
