一、前言钛是一种新兴的金属材料,但是,随着钛工业的发展和应用量的增长,出现了大量的废钛料。据估计,在海绵钛生产过程中约产生10％的废料;在生产钛材和钛制品时,废料约占金属料的80％。如何减少和回收如此大量的废钛便成为钛工业发展中一项急需解决的重大课题。美、苏在这方面进行了不 First, the foreword Titanium is a new metal material, however, with the development of titanium industry and the application of the amount of growth, there have been a lot of waste titanium material. It is estimated that about 10% of scrap is produced in the production of titanium sponge and about 80% of the metal material in the production of titanium and titanium products. How to reduce and recover such a large amount of titanium scrap has become an urgent need to solve the major issue in the development of titanium industry. The United States and the Soviet Union did not do so in this respect
