金属钽的精炼加工始于1959年，由矿石处理开始，制造碳化钽、氧化物和钽粉，后将重点移向电子束炉(EB)熔炼铸锭和加工材。加工材集中在电子材料上，以蒸发舟为主。1963年开始制造厚度为7μm的电子用钽箔和无缝钽管，1964年开发了钽板与其它金属板的爆炸复合板，并进行轧制，出
Tantalum metal refining began in 1959 with ore processing beginning with the manufacture of tantalum carbide, oxide and tantalum powder, with the focus shifted to electron beam furnace (EB) ingot casting and processing. Processing materials focused on electronic materials, mainly to the evaporation boat. Started in 1963 with a thickness of 7μm electronic tantalum foil and seamless tantalum tube, in 1964 developed a tantalum plate and other metal plate explosion composite plate, and rolling out
