难熔硅酸盐和岩石中存在难熔矿物的试样分解,在应用酸分解方面有加热加压熔样法分解难熔样品。应用无水偏硼酸锂熔样法,Shapiro以石墨坩埚代替铂坩埚以来,岩石全分析的流程有了很大的发展。对岩石、矿物样品的分解,文献[5—8]有专门论述。资料[9]推荐应用热解石墨坩埚代替铂、镍、银、刚玉坩埚。近几年来国内黑色冶金分析方面许多单位采用硼酸与碳酸钠或碳酸锂混合在石墨粉垫底的瓷坩埚中分解难熔矿物。我们曾采用 V.S.Biskupsky提
Samples of refractory silicates and rocks containing refractory minerals are decomposed, and in the application of acid decomposition, heated and pressurized molten samples are used to decompose refractory samples. Application of anhydrous lithium metaborate boil-off method, Shapiro graphite crucible instead of platinum crucible since the rock full analysis of the process has been greatly developed. The decomposition of rock and mineral samples has been discussed in detail [5-8]. Data [9] recommended the use of pyrolytic graphite crucible instead of platinum, nickel, silver, corundum crucible. In recent years, many domestic black metallurgy analysis units using boric acid and sodium carbonate or lithium carbonate mixed in graphite crucible at the bottom of the decomposition of refractory minerals.
