【Abstract】 The gassing property of four different sorts ceramic material were tested in vacuum environment by the testing device which designed by ourselves. On the bases of that and comparing with every surface and section SEM photos of the different ceramic materials. The reason why different materials generate different amount of gas in high temperature were analyzed .更多还原
