1989年西方国家的海绵钛生产量推定为45100～46600t,其中日本为20000～21500t,美国为24400t,英国为700t。海绵钛的需要量推定为45400～49800t,其中日本为14500～16500t(包括钢铁添加用海绵钛约2500t),美国为25700～27600t(包括钢铁添加用海绵钛约1600t),欧洲为5200～5700t。1989年整个西方国家海绵钛的需要量将出 In 1989, the production of titanium sponge in western countries was estimated to be 45100 ~ 46600t, of which Japan was 20000 ~ 21500t, the United States was 24400t, and the United Kingdom was 700t. The requirement of sponge titanium is estimated to be 45400-49800t, of which Japan is 14500-16000t (including about 2500t of titanium sponge added for steel), 25700-27600t (including about 1600t of sponge titanium for steel adding) in the United States and 5200-500t in Europe. The demand for sponge titanium in the entire Western countries will be out in 1989
