日本两大海绵钛巨头——大阪钛科技公司和东邦钛公司的海绵钛年产能到2011年3月末预计已达6.88万吨,比上一年度增加了20%。通过熔炼钛矿得到的海绵钛经过熔炼、成形得到钛锭,然后可制成各种合金应用于喷气式发动机、发电厂、石油、化学工厂。目前受新型飞机及世界范围内用钛需求增加的影响,今后需 Japan’s two major sponge titanium giant - Osaka Titanium Technologies and Toho Titanium sponge titanium annual production capacity by the end of March 2011 is expected to have reached 68,800 tons, an increase of 20% over the previous year. Titanium sponge obtained by melting the titanium after melting, forming titanium ingots, and then can be made of various alloys used in jet engines, power plants, petroleum, chemical plants. Currently affected by the increase in demand for new aircraft and worldwide use of titanium, the future needs
