Feldspar
Feldspar is a group of minerals that are abundant in the Earth's crust and are commonly found in igneous, metamorphic, and sedimentary rocks. In space and astronautical engineering, feldspar is of interest due to its potential use as a radiation shield. Feldspar has a low density and can effectively absorb and scatter ionizing radiation, making it a promising material for protecting astronauts and spacecraft from harmful cosmic rays. Additionally, feldspar can be used as a raw material for the production of ceramics and glass, which have a wide range of applications in space technology, such as for thermal insulation and optical components.
