Due to the small size of nano-alumina can be used to make artificial stones, analytical reagents and catalysts and nano-carrier for light-emitting materials can greatly improve its luminous intensity, ceramics, rubber toughened, several times higher than the average alumina in particular to improve the ceramic density, smoothness, cold and fatigue. Nano-alumina is mainly used YGA laser crystallization of the main components and integrated circuit substrate, and used in coatings to improve wear resistance.
