Microstructure and Properties of a Machinable Glass Ceramic with Low Melting Temperature

Abstract

Abstract: A new machinable glass ceramic with low melting temperature was prepared and its microstructure, machinability and mechanical properties varied significantly with the variation of crystallization temperature and time. The test results show that optimum machinability and higher bending strength can be obtained when the glass ceramic is heated at 600℃ for 6-8h or at 650℃ for 1~2h, and its bending strength can be further increased with rising crystallization temperature, but its machinability will be decreased rrapidly.

Key words: low melting temperature, machinable glass ceramic, crystallization, machinability, strength
