锰矿石和锰精矿 分析试样中吸湿量的测定 重量法

[中文适用范围]： 该方法基于将空气干燥的测试部分在105至110℃的实验室烘箱中干燥至恒定质量，并测量质量损失。 该测定应与同一分析样品的其他成分的测定同时进行，以便可以在绝对干燥的矿石的基础上计算其他成分的含量。 应结合 ISO 4297 一起阅读。 [外文原描述]： The method is based on drying of an air-dried test portion to constant mass in a laboratory oven at 105 °C to 110 °C, and measurement of the loss in mass. The determination is intended to be carried out simultaneously with that of other constituents of the same analytical sample, so that the contents of the other constituents can be calculated on the basis of the absolutely dry ore. Should be read in conjunction with ISO 4297.
