High temperature Al-Ca сondensate in lunar regolith

Cover Page

Abstract


For the first time in natural conditions in the samples of lunar regolith from the Mare Crisium (“Luna-24” station) a high-temperature condensate was found in the form of binary glass balls of dimensions in the order of 200-400 nm, consisting of an oxide Al-Ca core covered with an uniform film of high-silicon glass, containing iron nano-inclusions. Previously, high-temperature condensate was only theoretically predicted on the basis of laser evaporation experiments.
