▎ 摘  要

NOVELTY - A graphene toughened high-power LED cooling ceramic substrate comprises 30-40 pts. wt. aluminum nitride, 15-20 pts. wt. nano-aluminum nitride, 1-2 pts. wt. yttrium oxide, 0.3-0.5 pts. wt. graphene, 10-15 pts. wt. ionic liquid, 0.1-0.2 pt. wt. aluminum isopropoxide, 0.1-0.2 pt. wt. sodium hexametaphosphate, 0.4-0.5 pts. wt. tetraethoxysilane, 20-25 pts. wt. deionized water and the balance amount of dilute nitric acid solution. USE - Graphene toughened high-power LED cooling ceramic substrate (claimed). ADVANTAGE - The ceramic substrate has excellent sting effect, effectively reduces the oxygen content in the sintering atmosphere, improves thermal conductivity, has toughening effect and excellent thermal conductivity, reduces the brittleness of aluminum nitride ceramics, is tough, dense and not easily damaged, and has excellent performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of graphene toughened high-power LED cooling ceramic substrate.
