V_2O_5在高温时能完全分解碱土金属的硫酸盐。据此,首次建立了锶矿中测定天青石与菱锶矿的简便、快速而准确的化学物相分析方法:即以硝酸—硝酸锶溶液作为菱锶矿的选择性溶剂,由于同离子效应使天青石的溶解率降到最低的限度。将分离后的天青石灼烧,称重,加入适量V_2O_5再灼烧、
V2O5 can completely decompose alkaline earth metal sulfate at high temperature. Therefore, a simple, rapid and accurate chemical phase analysis method for the determination of celestite and stronta-strontium in strontium ore has been established for the first time: the nitric acid-strontium nitrate solution is used as the selective solvent for strontianite. Because of the same ion effect Celestite dissolution rate to a minimum limit. The separated celestite burning, weighing, adding appropriate amount of V_2O_5 and then burning,
