manufacturers in Europe developed methods to cast basalt that resulted in materials that were strong, nonporous, and chemically inert. Basalt casting should be feasible on the Moon and Mars; however, it is extremely energy intensive. An alternative to basalt casting that can enable early construction and part production is basalt sintering.

Basalt, diabase, granite, river stone belong to the high hardness and high silicon content material. In the actual crushing operations, they are more difficult to crush and have higher crushing cost. Therefore, the crushing process of these materials should be designed reasonably, taking into account of investment cost and production cost.
