据耳闻目睹的事实清楚可知,在八十年代,中国将对世界稀土的生产、市场和技术带来猛烈的冲击,而到1990年,则会在稀土许多领域的应用科学方面作出重要贡献。中国具有世界上最推厚的稀土资源,其蕴藏量约为36×10~6吨,比世界所有其它地区的总和还要多。当提炼技术和设备真正解决之后,中国将对世界市场上各种稀土材料的价格带来影响。尽管中国大多数金属均有足够的金属矿物,但铬和钴看来比较短缺。代用品研究强调要采用中国资源丰富的金属。球墨铸铁是采用Fe-Si-稀土合金生产的,取代了中国基本
It is clear from the facts we have heard and heard that in the 1980s China would have a violent impact on the world’s rare earth production, markets and technologies. By 1990, China would make an important contribution to applied science in many fields of rare earths. China has the world’s thickest rare earth resources, its reserves of about 36 × 10 ~ 6 tons, more than any other part of the world’s total. After refining technology and equipment are really resolved, China will have an impact on the prices of various rare earth materials in the world market. Although most metals in China have enough metallic minerals, chromium and cobalt appear to be in short supply. Substitutes emphasized the need to use China’s resource-rich metals. Ductile iron is produced using Fe-Si-rare earth alloy, replacing China’s basic
