The Reaction Densification of Ca-α-Sialon
Source abstract
Abstract
Ca-a-Sialon was synthesized by hot-pressing technique, and the reaction sequences and densification of Ca-a-Sialon vs sintering temperature were studied. It was found that Ca- a-Sialon isstable. At 1250℃ the reactant mixture stated to soften, and at 1300℃ gehlenite was producedin the system; and at 1500℃ gehlenite was resolved into liquid phase and at the same time Ca-Sialon formed; and at 1600℃ the reaction of formation of Ca-a-Sialon was finished and singlephase Ca-a-Sialon was got. Accompanied by the above sequences, the densification was finishedby liquid sintering through particle rearrangement, solution-reprecipitation, grain growth.
