铂铑合金在硅酸盐熔体中铂和铑损失的研究

摘要

Study of the loss of platinum and rhodium in silicate melts of platinum-rhodium alloy. At a certain temperature, platinum and rhodium were lose, and the loss of rhodium was 3.6~5 times of the amount of platium. And qualitative analysis the change of the section rhodium content of PtRh20 in long term use. As a result, the rhodium content was falled 30% to 50%.%研究了铂铑制品中铂和铑在硅酸恿熔体中的损失。发现了在一定温度下，铂和铑在硅酸恿熔体的作用下均会损失，其中铑损失量是铂损失量的3.6~5倍。并定性研究了PtRh20制品在长期使用后厚度方向上铑含量的变化，发现在使用18个月后PtRh20制品铑含量降低了30%~50%。
