Sintering of Alumina in Oxygen and Nitrogen Containing Liquids
Densification of inactive alumina powder was studied in the presence of nitrogen containing liquid, as well as in the presence of oxide liquids. It was found that considerably higher amount of additions forming nitrogen containing liquid was necessary to bring about full densification of alumina. Densification and grain growth take place more intense in the presence of nitrogen containing liquids. Properties of ceramics sintered in the presence of nitrogen containing liquids are as good as those of ceramics sintered in the presence of oxide liquids.
