METHOD FOR MANUFACTURE OF CERAMIC MATERIAL FOR ACCUMULATION OF HEAT ENERGY Russian patent published in 2022 - IPC C04B33/04 C04B35/447 C09K5/00 

FIELD: heat engineering.

SUBSTANCE: group of inventions relates to a method for the manufacture of ceramic material for accumulation of heat energy, ceramic material, a device for accumulation of heat energy. The method for the manufacture of ceramic material for accumulation of heat energy includes production of a mixture of at least clay particles and particles of natural and/or synthetic phosphate, and water, while the mentioned mixture contains from 0.5 to 40 wt.% of phosphate per the weight of a dry mixture not containing water, as well as molding and annealing of the specified mixture to obtain ceramic material. Ceramic material for accumulation of heat energy is also claimed. A method for accumulation of heat energy in ceramic material includes placement of a fluid heat carrier in contact with ceramic material in such a way that to transfer heat from the fluid heat carrier to ceramic material in a charge phase and transfer heat from ceramic material to the fluid heat carrier in a discharge phase. The device for accumulation of heat energy includes a tank containing ceramic material and a contour of circulation of the fluid heat carrier, connected via fluid to the tank in such a way that to provide a contact of the mentioned fluid heat carrier with ceramic material.

EFFECT: increase in heat conductivity and mechanical strength of ceramic materials.
