苏联科学院矿物学、地球化学和稀有元素結晶化学研究所的波利申科和李祖諾夫,新近研究了黑鎢矿中钪的分佈問題。並在該院出版的“地球化学”杂志1958年第3期中发表了他們的研究成果。研究的对象,包括苏联47个矿床中的450个黑钨矿标本。研究的方法,是採用光譜定量分析法:分析时挑选純淨的黑钨矿样品;在电弧中燃燒的試样量为~20毫克;照相时的电流强度为10安培(±2安培),电压为220伏特。在这种条件下鑑定钪的灵敏度接近于0.005％(以金屬計算)。鑑定的精确性为±15％。採用2552.359的譜綫作为钪的鑑定。
Polyshenko and Zizhnov, Institute of Mineralogy, Geochemistry and Rare-Earth Crystallization Chemistry, Soviet Academy of Sciences, recently studied the distribution of scandium in wolframite. And published their findings in the journal Geochemistry published in the hospital in issue 3, 1958. The subjects of the study included 450 wolframite specimens from 47 deposits in the Soviet Union. The method of study was the use of spectroscopic quantitative analysis: a sample of pure wolframite was selected for the analysis; the amount of sample burned in the arc was -20 mg; the current intensity at the time of photography was 10 Amps (± 2 Amps) at a voltage of 220 volts. The sensitivity of identifying scandium under these conditions is close to 0.005% (calculated as metal). The accuracy of the identification is ± 15%. The spectral line of 2552.359 was used as the scandium identification.
