氧化钇由于其特异的光学性质,已成为一种优良的荧光、激发和电光源材料。为适应国内外需要,南昌硬质合金厂在1968年兴建了一个氧化钇分离车间。原采用过P_(204)-HCl萃取体系分组和N_(263)-NH_4S_(CN)-HCl萃取转换体系,分离、提纯氧化钇产品。
Yttrium oxide has become an excellent fluorescent, excitation and electric light source material due to its specific optical properties. To meet the needs of domestic and foreign, Nanchang Carbide Plant in 1968 to build a yttrium oxide separation plant. The original system of P_ (204) -HCl extraction system and N_ (263) -NH_4S_ (CN) -HCl extraction and conversion system were used to separate and purify the yttrium oxide product.
