Effect of hot isostatically pressed sintering on microstructure of translucent alumina compact

“…Murray et al suggested that for estimating the relative density of compacts subject to HIP-sintering the model proposed by Mackenzie and Shuttleworth would be applicable because it accounts for the presence of porosity at the grain-boundary of sintered alumina [1]. The applied pressure enhanced by the coalescence of alumina grains which is stimulated by heating would be dominant against the capillary pressure inside the boundary pore [2,4].…”

“…It is well known that sintered polycrystalline alumina (PCA) which contains small grain size with high density could exhibit excellent mechanical and optical properties [1][2][3][4][5][6]. In general, physical properties of ceramic compacts fabricated from powdery ceramics are very sensitive to their microstructures which would be affected by their processing methods.…”
