Sapphire crystal material has a good transmittance and its infrared transmittance hardly changes with temperature. Therefore it is widely used in lasers, infrared technology, semiconductors, measuring instruments, defense and aerospace and many other areas. But there still have the problems of low productivity, easy scratching the surface and the surface quality of instability and others on the grinding...
Al2O3 single crystal has the following unique physical properties of high hardness, high toughness, obvious pleochroism and high refractive index Etc. The paper introduced the processing property of Al2O3 single crystal, described its grinding technology. Then analyzed the characteristics and status of grinding technology of the large-sized Al2O3 single crystal, combined with the relational research,...
