To investigate the self-assembled growth of organosilane molecules carrying Si, C and H to form multiple layers, samples were prepared in toluene and then transferred to TEM Cu grids coated with thin C films for TEM observation. It is surprising that micrometer sized flakes with a main composition of Mg and Si (or Al and Si) were occasionally observed in the TEM specimens, later were identified as lizardite-1T phase. To trace down the source of the inorganic particles, all procedures in the sample preparation were carefully checked. The particles of the lizardite-1T phase were confirmed from the organic solvent of toluene.
