Abstract The distribution of uranium between different phases of cast stone matrices fabricated by fusion of basalt and uranium-bearing SiO2-based collectors was investigated. It was found that matrices created by fusion of basalt with SiO2 consist of glass, quartz, and spinel as the main phases. A study of the physicochemical properties of collectors …

Basalt has specific heat of 0.84KJ/kg.K and density 3000kg/m3. Heating 1m3 of basalt from 0°C to its approximate melting point of 1250°C, would require some 3.15GJ of heat (~900kWh). Each kWh of electricity costs about $0.1 on average. So melting a cubic metre of basalt takes about $90 worth of electricity.

In the terrestrial environment, transportation cost is the basic limitation on the use of building materials such as sand, cement, gravel, and stones. Because of transport cost, local materials are preferred over imported, higher-quality materials. This is apparently the case for lunar and martian outposts as well, and this fact is augmented by the need to transport as little technological ...
