Assessment of thermodynamic parameters of the plasma chemical process for magnesium oxide production

Abstract

This work are presented the calculation results of thermodynamic parameters of the reaction of magnesium fluoride decomposition by ionized water vapor with the formation of solid magnesium oxide and gaseous hydrogen fluoride at atmospheric pressure in the temperature range from room temperature to 2800 • C . The calculation of the thermodynamic parameters was carried out with the Reaction Equations software module of scientific programs HSCChemistry package. Thermodynamic analysis of magnesium fluoride MgF 2 was carried out on a thermogravimetric analyzer TGA/DSC2. The thermodynamic parameters results are in good agreement with the results of thermogravimetric analysis. There were determined the optimum conditions for plasma-chemical processing of magnesium fluoride.

Magnesium Oxide Production by Plasma Chemical Conversion from Fluorine-Containing Industrial Waste

“…One of the ways to solve the problem of waste processing is the use of the plasmachemical method, i.e., the chemical method of producing highly dispersed powders of nitrides, carbides, borides, and oxides, which occurs in a reaction in low-temperature plasma far from equilibrium at a high rate of nucleation of new phase and their low growth rate. UMP JSC has developed a pilot plasma-chemical technology for obtaining magnesium oxides from magnesium fluoride waste [4,5]. Plasma pyrolysis is a modern technology that offers a promising future for the efficient treatment of solid waste [6][7][8][9].…”
