摘　　要：烧失减量是矿物的一个重要参数,利用热重分析仪首先测定矿物的吸湿水,然后测定矿物干基烧失增减量,综合分析铬矿、锰矿、铝矾土、铁矿、硅酸盐矿物,方法的标准偏差为0.014%;测定了几种国家标准物质和五水硫酸铜,测试结果与标准值基本一致,精密度和准确度均令人满意。Loss on ignition （LOI） is an important parameter of the minerals. The hygroscopic moisture is first determined and then the loss on ignition on dry basis by thermal gravimetric analyzer. The standard deviation of this method is 0. 014% by comprehensive analysis of chrome ore, manganese ore, bauxite, iron ore, silicate ores. Testing results of several national standard samples and copper sulfate pentahydrate are consistent with the standard values. Precision and accuracy of this method are satisfactory.
