| 摘 要： | 采用热重分析法(TGA)测量矿产品中的吸附水及烧失减量,验证了方法的准确性及精密度。对多种矿产品样品采用TGA法和常规马弗炉加热法进行测量,对比结果表明,这两种方法没有显著性差异。TGA法具有方便快捷、准确可靠等优点,是矿产品吸附水及烧失减量检验的首选。

| Abstract: | The absorbed water and loss on ignition in mineral products were studied by thermogravimetric analysis（TGA）method.The accuracy and precision of the method were validated.Several mineral products were tested by TGA and common muffle furnace burning method.By comparison,it concluded that there was no significant difference in the analysis results between the two methods.But the TGA method has some advantages such as convenience,higher accuracy and reliability,thus it is the preferred method that should be used for the determination of absorbed water and loss on ignition in mineral products. |
