Gas Pressure Sintering of β-Si_3N_4 SHS
Source abstract
Abstract
β-Si3N4 inaterial prepared by self-propagating high-teinperature synthesis from silcon powder and nitrogen was studied by gas pressure sintering process. The effects of different ainounts of YAG additive and holding time on the properties were investigated. The results show that this β-Si3N4 powder can be sintered to99% of the theoretical density with high fracture toughness under the sintering conditions of 1.2MPa Ar pressure 1940℃ and ho1ding 1 hour.
