The technology of molten salt oxidation (MSO) is a thermal treatment process mainly used for reprocessing of hazardous organic waste. This technology is considered as an alternative to the conventional incineration processes. The principle of the whole technology is based on flameless oxidation of materials in the molten salt with the consequent capture of gaseous products in molten alkaline salts. The melts with low melting point and high viscosity, such as a ternary mixture of carbonates Na2CO3, K2CO3, and Li2CO3, are the most used in this technology. However, the molten salts create a very corrosive environment for metal and ceramic materials, so the main aim of this experimental work was to determine the resistance of corundum samples, which were prepared by plasma spraying, and to find out its potential use as the protection of the reactor metal surface.
