Crystal formation during thermal oxidation of shungite

▪ Tovpenets, Y.Yu. (2023): Crystal Formation During Thermal Oxidation of Shungite. Zapiski RMO. 152(4), 116-122.

Using scanning electron microscopy and Raman spectroscopy, micro-sized crystals formed during the thermal oxidation of shungite were studied. The crystals have been identified as bultfonteinite, "allanite" and cornubite; they were not found in the original shungite sample. It has been suggested that the mechanism of microcrystal formation is desublimation (crystallization from the gas phase).
