前几年,国内锗材料生产厂家因原料猛涨导致成本增高,市场需要量也减少,南京锗厂也和其他厂家一样,面临着亏损的严峻考验。当他们了解到国际上有相当数量的锗原料因含有硅和铅等有害成分,有出售到国外冶炼的意向,南京锗厂就通过外贸部门合作,从苏、英、美、奥地利等国家购进这类锗原料,同时抓紧时间组织技术攻关,解决了冶炼过程中的污染 A few years ago, the domestic germanium material manufacturers due to raw material soaring costs lead to increased market demand, Nanjing Germanium plant and other manufacturers are also faced with the severe test of loss. When they learned that a considerable amount of international raw materials for germanium contain harmful components such as silicon and lead, and have the intention to sell to foreign countries, Nanjing Gerium Factory, through cooperation with foreign trade departments, purchased from countries such as the United States, the United Kingdom, the United States and Austria Such germanium raw materials, while seize the time to organize technical research to solve the pollution in the smelting process
