目前世界上仅有苏联、日本、美国、英国及中国五个国家生产海绵钛,据统计至1982年6月底总产能力已超过110000吨/年,其所用工艺及生产能力见表1。现行工业生产海绵钛的工艺有克劳尔镁还原法、享特钠还原法及四氯化钛熔盐电解法三种。其中,镁法产量为98070吨/年,占 At present, only the United States, the United States, Britain and the United States of the world have produced titanium sponge in five countries. According to the statistics, the total production capacity of the titanium sponge has exceeded 110,000 tons / year by the end of June 1982, and its technology and production capacity are shown in Table 1. The current industrial production of titanium sponge technology have Klaurd magnesium reduction method, enjoy the special sodium reduction method and titanium tetrachloride molten salt electrolysis three. Among them, the magnesium production was 98070 tons / year, accounting for
