The vessel material is very hard, but rather low density so its crushing rate is rather slow. 5 minute grinding times, or more, are typically necessary. While hard, the vessel is very brittle and somewhat friable. Tiny, ~100 µm chips occasionally flake off the puck. The aluminum oxide vessel only has a puck, a bowl, and a lid.

Jan 05, 2014 · The data on the experimental determination of surface tension coefficients (σ) of tungsten carbides WC and WCW2C by the force of simultaneous grinding their powders with iron powder in a RM 400 planetary mill are presented. Coefficients σ are evaluated and confidence intervals of their expected values are determined.
Oct 10, 2012 · Features of phasestructure formation and abrasive wear resistance of composite coatings "WCM2 steel" worn against tungsten monocarbide have been investigated. It was established that adding 20 wt.% WC to the deposited powder mixture leads to the increase in M 6 C carbide content. These carbides show a multimodal size distribution consisting of ~ μm eutectic .
