人们在研究锂或锂辉石在陶瓷中应用的时候,常常需要测定锂在陶瓷或玻璃中存在的量。一般来说,锂的测定分两类,一类是测定耐火材料中β-锂辉石或α-锂辉石的含量,另一类是测定氧化锂的总量。x—射线法测定α—或β—锂辉石精矿或矿体中的α-或β-锂辉石的含量,可用消失 X-射线法来进行测定。用这种方法进行测定时,应制备一系列不同含量的α-或β-锂辉石标准样品,用于 X-射线衍射分析,测定两条“d”谱线4.21和2.93,这种“d”谱线对干矿物最为灵敏。该方法测
When studying the application of lithium or spodumene in ceramics, it is often necessary to determine the amount of lithium present in the ceramic or glass. In general, the determination of lithium divided into two categories, one is the determination of refractory β-spodumene or α-spodumene content, the other is the determination of the total amount of lithium oxide. The content of α- or β-spodumene in α-or β-spodumene concentrate or ore body measured by x-ray method can be measured by vanishing X-ray method. In this method, a series of different samples of α- or β-spodumene should be prepared for X-ray diffraction analysis to determine 4.21 and 2.93 of the two “d” lines. This "d The spectrum is the most sensitive to dry minerals. The method of measurement
