文摘

Various methods for obtaining highly dispersed sodium chloride in the form of powders and sols in organic solvents were studied and compared. These include the mechanical grinding in a ball mill, laser ablation, cryochemical method, solvent-substitution method, pyrolysis of an aerosol, and a number of chemical methods. The samples obtained were examined by X-ray diffraction, elemental analysis, transmission electron microscopy, and dynamic light scattering technique. The methods for obtaining highly dispersed NaCl were compared in three basic parameters: size of particles being obtained, their size distribution, and productivity. It was shown that, depending on a method used, sodium chloride particles with average sizes in the range from 15–30 nm to 10–20 μm can be obtained.
