| 摘 要： | 利用陶瓷纤维直径不同的特点,采用一步成形的方法制备具有梯度结构的纤维多孔陶瓷。采用扫描电镜(SEM)和金相显微镜对纤维多孔陶瓷的显微结构进行表征,并对影响材料性能的各种因素进行分析。结果表明:800℃烧成样品的抗折强度为6.7 MPa,气孔率最大达到76%,室温下空气流速为1 m/min时的过滤阻力为98 Pa,过滤阻力随着烧成温度的上升而逐渐下降。

| Abstract: | The fibrous porous ceramic fiber with different diameters for purifying high temperature dust gas was fabricated by one step with pore-gradient structure.The microstructure features were characterized by scanning electron microscope(SEM),and metallographic microscope.Factors affecting the properties of the materials were analyzed.Results showed that the suitable preparing conditions were as follows:the temperature of 800 ℃,the rupture strength of 6.7 MPa,and the porosity of 76%.The permeation resistance of the sample was 96 Pa(at the room temperature) on the air rate of 1 m/min,and the sample resistance decreased with the rising of firing temperature. |
