I've done a fair amount of research on chromium oxide. The kind we use is Chromium (III) Oxide CR2O3. It's a non-toxic version of chromium oxide.

I recall receiving a spec sheet after much back and forth from a Chromium Oxide manufacturing rep which listed an average particle range of different grades of chromium oxide. The largest average particle range in one of the available grades in descending order was 1.7 micron, .8 micron, .7 micron and .6 micron with different purity levels even within those four categories.

I guess that means that chrome ox is available in different particle ranges other than ".5 micron". I put the quotes around the .5 micron for a reason since it would be inaccurate for any supplier or manufacturer of any abrasive to state that ALL particles in an abrasive media would be guaranteed to be the exact same particle size. In our beloved ".5 micron" chrome ox, we've come to believe, we'd like to believe or we think we're certain that we're using a powder that contains only .5 micron particle chrome ox. That's only an average no matter where it comes from.
