Eminess Technologies offers two different lines of aluminum oxide powders; the R and M lines. These powders were developed
primary for the metallography and precision optics industries and are 99.99% pure.
Ultra-Lox™ R Standard Alumina Powders
This series of powders is ideal for less stringent polishing applications where a totally
scratch-free surface is not necessary. They have the unique ability to break down during the polishing
process to produce nicely polished surfaces, but with a coarser surface roughness than that which can
be obtained with the Ultra-Lox™ M powder series.
Ultra-Lox™ M Agglomerate-Free Alumina Powders
The agglomerate-free or M line of the Ultra-Lox™ powders are R powders that have been subjected
to a proprietary process wherein most of the larger agglomerates have been broken down. This powder is for
polishing applications where the R powder produces too many scratches or there is a need of a better final surface
quality.
NOTE ON DIFFERENCES BETWEEN THE R AND M SERIES POWDERS: In both the R and M series, the size of the alumina
particles is called the "Functional Particle Size". In the R series, these particles can agglomerate into larger
particles. Under most standard polishing pressures, most of these larger agglomerate particles will be broken down into
their functional particle sizes. In the M series, a proprietary process is applied so that most of these agglomerate
particles will be broken down to their functional particle size prior to the polishing process.
