Heat Resistance of Nanocrystalline Powders, Single Crystals, and Coatings of CrSi2 Obtained from Molents in the molten Sn–Zn system. CrSi. coatings were obtained by electroless deposition of Si onto pure Cr substrate surface from molten KCl–NaCl–NaF–Na.SiF.–Si system. The heat resistance of the nanocrystalline powders, single crystals, and coatings to oxidation in air at elevated temperatures was
