Abstract
Since ceramics are generally produced by sintering of compacted powders, a certain quantity of gases which are in the sintering atmosphere or absorbed on the surfaces of the raw powders must be retained in the sintered body. These gases have been believed to inhibit pore shrinkage at the final stage of sintering. Large residual pores are known to deteriorate the strength of sintered compacts because they act as a fracture origin, and small pores may decrease properties such as hardness, wear resistance, thermal conductivity, etc. It is probable that the gases themselves are deleterious to strength or wear resistance by reducing grain boundary strength. Thus, it is important to analyze gases contained in the sintered body and to decrease their amounts in order to improve the properties of ceramics. This paper describes gas evolution behavior during fracture of Al{sub 2}O{sub 3} ceramics as a first step in elucidating gas related problems in ceramics.
