Monolith perovskite catalysts for high-temperature applications (fuels combustion, toxic wastes incineration, hydrocarbons reforming, sulfur dioxide reduction, etc.) were elaborated. Basic stages of these catalysts manufacturing ( synthesis of perovskites ultradispersed powders via effective wasteless plasmochemical and mechanochemical routes, monoliths shaping by extrusion with subsequent drying and calcination) were developed. Pilot testing in a number of high-temperature catalytic processes demonstrated efficiency, thermal stability and thermal shock resistance of monolithic perovskites.
