METHOD TO HEAT FLUID MEDIUM AND PRESSURE-CAST ELEMENT Russian patent published in 2011 - IPC H05B3/14 

FIELD: information technologies.

SUBSTANCE: method to heat fluid medium includes stages of providing a pressure-cast element, which contains a ceramic material with a positive temperature ratio and content of less than 10 million parts of metal admixtures, and using the pressure-cast element to heat fluid medium. The pressure-cast element contains ceramic material with the positive temperature ratio and content of metal admixtures of less than 10 million parts, pieces of the pressure-cast element are made with the possibility of fluid medium circulation along them. The heating system, in which the pressure-cast element is arranged inside the cylindrical body, around which the fluid medium flows.

EFFECT: production of pressure-shaped types of source stocks with low extent of abrasion without loss of the required electric properties of cast PTR ceramics.
