Abstract

The invention relates to an iron alloy fusing sample preparation method for X-ray fluorescence spectrum analysis, belonging to the technical field of materialization detection and aiming to solve the problem that fusing a film production alloy sample can erode a platinum crucible. The method comprises the steps of building up wall of the platinum crucible, preparing an oxidizing agent, pre-oxidizing an iron alloy sample and fusing and preparing sample from the iron alloy sample. The invention provides the fusing sample preparation method suitable for various iron alloys such as ferromanganese, silicomanganese, calcium silicon, ferrosilicon, ferromolybdenum, ferrotitanium, cymrite, ferrochrome, ferrocolumbium, ferrovanadium, silicon silicomanganese and the like. By adopting the method, a glass fusing piece can be manufactured without eroding the valuable platinum crucible, the sample can be completely oxidized in the sample preparation process, the sample preparation time is short, the prepared glass fusing piece is uniform and perfect, and the mineral effect and the granularity effect can be completely eliminated. The invention has safe and reliable method, simple and convenient operation and good repeatability, is suitable for various iron alloy samples and widens the application range of the fluorescence analysis.
