Beryllium Oxide Powder Microstructure During Production Processing

Abstract

Beryllium carbonate and hydroxide powders are studied during production processing in order to prepare pure BeO powder. Powders are supplied by the Ul’binsk Metallurgical Plant (Kazakhstan Republic). It is established that beryllium oxide powder crystallinity and morphology depend to a considerable extent on production treatment type and regimes. Microphotographs of different powder batches point to a genetic connection of their morphology with type of starting raw material, which in turn may have a marked effect on slip and press-mix preparation, on molding, and also on sintering of ceramic objects and their properties.
