Expansion Coefficient of Sealing Material for Ceramic Metal Halide Lamps

摘要：

　　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.It is different with the quartz tube,after heating softly,ceramics tube cant stick with metal electrode lead together through squeezing.For the sealing,it is necessary to adopt the appropriate sealing materials.In our research work,studied the thermal expansion coefficient of the Al2O3-Dy2O3-SiO2 sealing material was a key for ceramic metal halide lamp.
