Abstract

This invention is a growth approach for sapphire crystal, The main process is: grinding the Al2O3 powder to ultra-fine particles, purifying the particles to above 99.999% purity, spray drying and adding organic binder, compacting, putting into the ultra high-temperature vacuum furnace and pre-sintering to produce Al2O3 semi-product, heating the semi-product to liquid phase and then solidifying and cooling it for crystal growth. This approach can shorten the growth period and save the cost. The crystal size is not limited and the quality satisfy the requirements of high performance optics, semiconductors, and communication devices as well.
