日本大同制钢公司研制出一种用电子束熔炼生产的高纯钼(99.9999％)材料,该公司声称:电子束熔炼过程中,在高真空炉内阴极灯丝产生的电子对着靶金属被加速并被轰击,以便在高温下熔炼和精整金属。据说,这种方法对于熔炼钼和其它高
Japan’s Datong Steel has developed a high-purity molybdenum (99.9999%) material produced by electron beam melting, which claims that the electron produced by the cathode filament in a high vacuum furnace is accelerated against the target metal during electron beam melting And bombarded to smelt and finish the metal at high temperatures. It is said that this method for the melting of molybdenum and other high
