Abstract
The invention is to implement both sol-gel process and burning process to form high quality fine or ultra fine particle powder. The particle is synthesized through high temperature flame and in extremely small dimension. Due to the high-speed synthesis, the lattice of particle or grain is oriented per its crystal habit; thus the quality of particle powder is very high. Besides that, a physical evaporation process can be conducted in a non-vacuum environment. Except some carbon oxide, the air pollution caused by this invention will be extremely low. This invention can provide high quality and ultra-fine particle powder and a process of non-vacuum physical evaporation with extremely low air pollution.
