不同的晶化温度和保温时间对低熔点可切削微晶玻璃的微观组织形貌、切削性能和力学性能有明显影响. 试验表明, 600°C保温6～8h与650°C保温1～2h的晶化效果等同, 具有最佳的切削性能和较高的抗弯强度. 更高温度晶化可使强度进一步提高, 但切削性能急剧下降.
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 600C for 6～8h or at 650C for 1～2h, and its bending strength can be further increased with rising crystallization temperature, but its machinability will be decreased rapidly.
