The frit sealing material is a crucial material in ceramic metal halide lamps.
陶瓷金属卤化物灯用封接材料是陶瓷金卤灯的关键材料。
In order to make a good ceramic metal halide lamps,to form the solid hermetic sealing supplied by the ceramic discharge and metal electrode is very important.
为了制造性能良好的陶瓷金卤灯,保证陶瓷放电管和金属电极引线之间形成牢固的气密性封接是一个关键,和石英管不同,陶瓷管无法在加热软化后通过挤压与金属电极引线粘合在一起,为了完成放电管和电极的密封,必须采用合适的封接材料将它们封接起来,因此对陶瓷金卤灯的关键材料 Al_2O_3-Dy_2O_3-SiO_2系封接材料膨胀系数进行了研究。
