Self-propagating high-temperature synthesis of ultradisperse molybdenum disulfide

The synthesis of molybdenum disulfide in a combustion wave, from mixtures of sulfur with ultradisperse molybdenum powder obtained by electrical explosion of wires, is investigated. Experimental data are give on the combustion rate and temperature and the degree of conversion to the final product as a function of the pressure and component ratio. It is shown that the process corresponds to a parabolic law with an activation energy of 80 J/mole and be described by an elementary model of combustion of the second kind. Optimal conditions of synthesis with a yield of up to 99% are determined.
