全世界黑色和有色金属粉末的生产在高速发展。七十年代的年增长速度大于9％。全世界铁粉目前的生产能力每年约为50万吨以上(见表1)。 1970～1979年间,铁粉和铁基合金粉的产量,北美增加约70％,日本增加约110％,瑞典和欧洲为20～30％。而铜粉和铜基合金粉的产量,北美约增加20～30％,日本约增加90％,钼粉的产量,北美、日本增长约一倍。由于航空工业高温合金的应用增加,北美镍粉产量增长近五 Production of black and non-ferrous metal powders worldwide is rapidly growing. Seventies the annual growth rate of more than 9%. The world’s current production capacity of iron powder is about 500,000 tons per year or more (see Table 1). Between 1970 and 1979, iron and iron-based alloy powder production increased by about 70% in North America, about 110% in Japan and 20-30% in Sweden and Europe. The copper and copper-based alloy powder production, North America increased by about 20 to 30%, Japan increased by about 90%, molybdenum powder production, North America, Japan doubled. Due to the increased use of aerospace superalloys, nickel powder production in North America has grown nearly five
