Effects of ground alumina powder on grain growth of plate grains
1997 - 1999
Investigating Researcher (2)：
Two kinds of alumina powder with almost equal average particle size, weight particle size distribution and impurity content, namely, ground powder and build-up powder were studied on their sintering property. Any powder showed production of plate grains in sintered body, while ground powder produced plate grains at lower burning temperature in a shorter time. This might be because ground powder contained more particulates in each size of 0.1 μm/.
