Abstract

Microstructural characteristics of alumina-based porous ceramics are studied using scanning electron microscopy and X-ray analysis. Ceramic samples obtained by slip casting of commercially pure Al2O3 powder and sintered at the four temperatures 1300, 1400, 1500, and 1600 °C are studied. The three-point bending strength is determined for all the samples. A detailed microstructural analysis of the samples is carried out. Porosity of the samples, grain and pore size are found. The influence of structural features of the samples on their physicomechanical characteristics is investigated.Microstructural characteristics of alumina-based porous ceramics are studied using scanning electron microscopy and X-ray analysis. Ceramic samples obtained by slip casting of commercially pure Al2O3 powder and sintered at the four temperatures 1300, 1400, 1500, and 1600 °C are studied. The three-point bending strength is determined for all the samples. A detailed microstructural analysis of the samples is carried out. Porosity of the samples, grain and pore size are found. The influence of structural features of the samples on their physicomechanical characteristics is investigated.
