用于电真空和电加热材料的钼丝,是采用粉末冶金方法,由钼精矿到钼酸铵、MoO_3、Mo 粉,经压坯、烧结以后,加工制作成各种规格和性能的钼丝。现在,国内钼丝生产厂家约有十七家,一九八六年钼丝产量约4亿米,其中轻工部系统生产2.4152亿米,基本满足国内市场的需要。八十年代以来,随着改革、开放政策的逐步深入,国内先后
Molybdenum wire for electric vacuum and electric heating materials is made by powder metallurgy method from molybdenum concentrate to ammonium molybdate, MoO_3 and Mo powder. After pressing and sintering, molybdenum wire with various specifications and properties is processed . At present, there are about 17 domestic manufacturers of molybdenum wire and about 400 million meters of molybdenum wire produced in 1986, of which 241.52 million meters are produced by the Ministry of Light Industry, basically meeting the needs of the domestic market. Since the 1980s, with the gradual deepening of reform and opening-up policy, China has successively followed
