A High-Temperature Al–Ca Condensate in the Lunar Regolith

详细

For the first time, a high-temperature condensate in the form of two-component glass beads of about 200–400 nm size, consisting of an Al–Ca oxide core rimmed by a uniform oxide film of high-silica glass containing iron nano-inclusions, has been found in natural samples of the lunar regolith from Mare Crisium (Luna-24). Earlier, a high-temperature condensate was only theoretically predicted on the basis of laser evaporation experiments.
