SiBCN陶瓷的抗氧化性能
Oxidation Resistance of SiBCN Ceramics
摘要
Abstract
The oxidation behavior of SiBCN ceramics, derived from pyrolysis of polymeric precursor, was investigated by oxidizing the SiBCN ceramics at 1 200°C under air for different time. As a reference, SiCN ceramic was studied using the same process. The results show that after oxidation for 10 h, the weight gain of SiBCN is only 0. 35% and the ceramic keeps its original morphology without cracks. Whereas, the oxidation of SiCN results in a weight gain of 3.10% and cracks. The elemental composition of the sample surface is mainly SiO2 for SiBCN and SiO, ( x<2 ) for SiCN ceramics, respectively.关键词
