摘要
利用等离子体的高温和高传热率快速烧结陶瓷材料是一项新技术.在常压开口式高频等离子体中烧结了氧化铝,并测定了试样在高温尾流的温度分布和相应的密度曲线.采用两种粉混合,可以调节素坯孔分布和烧结活性,使试样快速烧结达到理论密度的99.1%.试验表明:常压等离子体烧结氧化铝陶瓷的密度取决于原料组成、样品尺寸及样品所处烧结位置.
It is a new technology to sinter ceramic materials rapidly by means of the high temperature and high heat transfer rate of plasma. Alumina was sintered in a high frequency plasma at normal pressure, and the temperature distribution and corrseponding density curve of the samples in the high temperature wake was determined. The pore distribution and sintering activities of the blanks can be adjusted by mixing two powders, thus getting the samples sintered rapidly with a density reaching to 99.1% of the theorectical value.The experiment has shown that the density of the alumina ceramic sintered by normal pressure plasma depends on the raw material composition, the sample size and the sintering position of the samples.
