The grinding of Si/sub 3/N/sub 4/ powder using reaction bonded Si/sub 3/N/sub 4/ attrition, vibratory, and ball mills with Si/sub 3/N/sub 4/ media was examined. The rate of particle size reduction and the change in the chemical composition of the powder were determined in order to compare the grinding efficiency and the increase in impurity content resulting from mill and media wear for each technique. Attrition and vibratory milling exhibited rates of specific surface area increase that were approximately eight times that observed in ball milling. Vibratory milling introduced the greatest impurity pickup. 7 references.
