摘要
本文主要研究了碳化硅多孔陶瓷孔隙率的影响因素以及烧结工艺对碳化硅多孔陶瓷材料性能的影响。碳化硅多孔陶瓷孔隙率的大小直接影响其烟气的过滤效率,通过研究碳化硅骨料的粒径,碳化硅的含量以及造孔剂含量对孔隙率和孔径大小的影响因素,实现了对碳化硅多孔陶瓷的孔隙率大小的有效控制。同时对碳化硅多孔陶瓷的烧结工艺中的烧成气氛和烧成温度进行了研究,研究发现,在弱氧化气氛下,烧成温度为1330℃时制备的碳化硅多孔陶瓷具有较高的孔隙率和较为优异的力学性能。
In this paper,the influence factors of porosity and sintering process on the properties of SiC Porous ceramics were studied.The filtration efficiency of porous SiC ceramics porosity were directed influence by the size of the flue gas,through the study influence factors of silicon carbide particle size,fsilicon carbide content and pore forming agent content on the porosity and pore size,to achieve effective control the porosity of porous SiC ceramics.At the same time,the sintering process of porous silicon carbide ceramics in the sintering atmosphere and sintering temperature were studied,the study found that in the weak oxidizing atmosphere,the preparation of porous silicon carbide ceramics with high porosity and good mechanical properties at 1330 degrees centigrade.
