WO1989012505A1 - Grinding process - Google Patents

The grinding of ceramics such as zirconia to fine powders free of organic contamination is achieved by using ammonia or a volatile amine as a dispersant. The grinding is preferably carried out in an attritor with fine (0.8-3.0 mm) grinding media. The process yields a fine, high purity powder suitable for use in the manufacture of ceramics articles.
