岩石、矿石氟含量测定，样品前处理采用高温热解法，一般高温热解法除需要管式高温炉成套装置外，热解过程各时段还需通入不同流速的水蒸汽，同时还要通入氧气。热解一个样品需３０ｍｉｎ，所以在测定时受到限制。本研究用催化助熔剂代替一般热解法的石英砂与样品混合，省... Rock and ore fluoride content determination, sample preparation using high-temperature pyrolysis method, the general pyrolysis method in addition to the need for tube-type high-temperature furnace complete sets of devices, the pyrolysis process also need to access the flow of steam at different times, but also through Into oxygen. Pyrolysis of a sample takes 30min, so the determination is limited. In this study, a catalytic flux instead of the general pyrolysis of quartz sand mixed with the sample ...
