Abstract

The interaction of Ra(NO₃)₂ and RaCO₃ with metallic Fe, Ni, Cr, Ti has been studied. Experimental samples were fabricated by deposition of water-alcohol suspensions of radium salts onto substrates made of the corresponding metals, followed by evaporation and calcination for 7–14 h at a temperature of 800°C. According to the results of an X-ray phase analysis, mixed oxides of composition RaMO_x, where M = Fe, Cr, Ti, Ni, in joint calcination of Ra(NO₃)₂ and RaCO³ with Fe, Ni, Cr, Ti metals.

镭盐与建筑材料相互作用的研究

摘要

研究了Ra(NO ₃ ) ₂和RaCO ₃与金属Fe、Ni、Cr、Ti的相互作用。实验样品是通过将镭盐的水-醇悬浮液沉积在由相应金属制成的基材上，然后在 800°C 的温度下蒸发和煅烧 7-14 小时来制造的。根据 X 射线相分析的结果，在 Ra(NO ₃ ) ₂和 RaCO ³与 Fe、Ni、Cr 的联合煅烧中，组成为 RaMO _{x 的}混合氧化物，其中 M = Fe、Cr、Ti、Ni ，钛金属。
