用熔融后的四硼酸锂制作铂金坩埚保护层,以BaO2做氧化剂,在马弗炉内通过逐渐升温来氧化锰铁合金,然后熔融制取玻璃熔片,用X射线荧光(XRF)光谱分析锰铁中硅、锰和磷含量。本法有效消除了锰铁合金熔融制样过程中的坩埚腐蚀问题,分析误差可完全控制在国家相关标准允许的偏差内,实现了锰铁合金各元素的快速准确测定。 The melted lithium tetraborate was used to make the protection layer of platinum crucible, the oxidizing agent of BaO2 was oxidized, and the ferromanganese alloy was oxidized by the gradual warming in a muffle furnace. Then, the molten glass was melted to make the glassmelt. The X-ray fluorescence (XRF) Silicon, manganese and phosphorus content. This method effectively eliminates the problem of crucible corrosion during the process of sample preparation of molten ferromanganese. The analysis error can be completely controlled within the allowable deviation of relevant national standards, and the rapid and accurate determination of each element of ferromanganese alloy is achieved.
