Abstract
Three kinds of additives were added into Ca alpha -sialon. (Ca0.6Si10.2Al1. 8O0.6N15.4). It was found that the additives resulted in more of the liquid phase during sintering. which promoted the completion of the alpha --> alp ha' transformation and the development of the elongated morphology characte ristic of alpha -sialon grains. Comparison was made concerning the effect o f the amount and type of additives on the microstructural development of Ca alpha -sialon. Phase and property analysis was also carried out on the hot -pressed samples. (C) 2001 Elsevier Science B.V. All rights reserved.
