| Abstract: | HBN based ceramic parts were prepared by self propagating high temperature synthesis technique.By cold isostatic pressing,compacts with 48% porosity were made from B powder with addition of HBN or SiO 2.BN based ceramic components were manufactured by the reaction of the compacts and 80MPa N 2.The relative density of the pure HBN parts is 68%,and the relative density of the HBN parts with SiO 2 addition is 78%.The XRD phase analysis and SEM fracture morphology analysis of the synthesized products were carried out. |
