Abstract

This work examines cast stone matrices (CSM) fabricated by comelting of basalt with both uranium-bearing perlite (M150 grade) and U₃O₈ at a temperature of 1623 K in air for 5 h. As a result of comelting of basalt with uranium-free M150 grade perlite, matrices are obtained containing glass and spinel as the major phases. When basalt is comelted with uranium-bearing perlite (M150 grade) CSMs are formed, the major phases of which are two Cr-spinels of different compositions, uranium-bearing glass, and dendritic aluminosilicate crystals. In the case of fusion of basalt and U₃O₈ taken in the initial weight ratio of 1 : 1, CSM is generated as the major phases containing UO₃, CaU₃O₁₀, (Al,Cr,Fe)₂U₂O₉, plagioclase, and uranium-bearing glass. The leaching rate of uranium from a basalt melt with uranium-bearing perlite (M150 grade, ~7.2 wt % U) and that of CSM made by comelting of basalt with U₃O₈, (~42.5 wt % U) after 28 days contact with water at 298 K was investigated.

含铀铸石基质

本文研究了玄武岩与含铀珍珠岩（M150 级）和八氧化三铀在 1623 K 的温度下于空气中熔融 5 h 而形成的铸石基体（CSM）。玄武岩与含铀珍珠岩（M150 级）重熔后形成 CSM，其主要相为两种不同成分的铬尖晶石、含铀玻璃和树枝状铝硅酸盐晶体。如果玄武岩和八氧化三铀的初始重量比为 1:1，则生成的 CSM 的主要相为三氧化三铀、CaU3O10、（Al,Cr,Fe）2U2O9、斜长石和含铀玻璃。研究了含铀珍珠岩（M150 级，约 7.2 wt % U）的玄武岩熔体中铀的沥滤率，以及玄武岩与 U3O8（约 42.5 wt % U）在 298 K 温度下与水接触 28 天后熔融而成的 CSM 中铀的沥滤率。
