简介 |
The present invention relates to aluminum nitride ceramics with high strength obtained by sintering a sintering material including an oxide having alkaline earth metal and zirconium; and rare earth metal oxide and an aluminum nitride (AlN) raw material powder and a low temperature sintering thereof. The aluminum nitride (AlN) ceramics obtained by the present invention may be sintered at a low temperature to have excellent mechanical properties.(AA) Step of preparing aluminum nitride (AlN) and raw materials for sintering(BB) Step of forming a slurry by mixing and crushing the raw materials(CC) Step of dehydrating and forming the slurry(DD) Step of sintering powderCOPYRIGHT KIPO 2015 |
