Summary

A statistical study of the ball milling of Si3N4 powder in Si3N4 hardware was undertaken to understand how the resulting increase in specific surface area is related to solids loading and mill speed. An attempt to optimize milling conditions was also made. The degree of comminution was more dependent upon solids loading than mill speed. A practical grinding limit between 0.5 and 0.75 μm was achieved in 144 h, independent of solids loading. Ball mill wear and media wear were independent of both solids loading and mill speed.
