引言烧结金属和合金粉末过滤器的发展是于1930年以制造表铜过滤器开始的。当前市场上的过滤器材料有各种合金、氧化和复合材料。_ 凡是要用耐腐蚀过滤器的地方,首先用陶瓷材料。这类材料既能耐各种中性,氧化以及绝大多数还原气氛,而且能耐绝大多数酸;温度较高时也能使用。然而它们的使用 Introduction The development of sintered metal and alloy powder filters began in 1930 with the manufacture of copper filters. Filter materials on the market today are available in various alloys, oxidized and composites. _ Where to use corrosion-resistant filters where the first ceramic material. These materials are resistant to all types of neutral, oxidized and most reducing atmosphere, and most of the acid resistance; can also be used at higher temperatures. However, their use
