Abstract

A method for manufacturing a high-temperature sintered body capable of energizing and heating, firstly producing a conductive carbon material precursor, then wrapping an insulating material precursor on the outside of the conductive carbon material precursor to obtain a blank body, and then pressing the blank body to obtain a molding The formed body is not loose when standing, and then the formed body is sintered under oxygen barrier conditions until the conductive carbon material precursor is carbonized into a conductor and the insulating material precursor is cured into an insulator, and then the sintering is completed. The high-temperature sintered body capable of energizing and heating is obtained. The electric heat utilization rate of this design is high.

Description

technical field [0001] The invention relates to a production process of an electrified heating body, in particular to a manufacturing method, a product and an application method of a high temperature sintered body capable of electrification and heat generation, and is particularly suitable for improving the utilization rate of electricity. Background technique [0002] In the existing floor heating type heating, the heating wire (the heating wire is composed of metal resistance wire or carbon fiber) is usually buried under the tile, and the heating wire is energized to generate heat and dissipate the heat into the room through the surface of the tile, so as to heat the room and keep warm. This process of electrification and heating has the following defects: 1. The utilization rate of electric heating is not high, and interlayer thermal barriers will be formed between the heating layer formed by the heating wire and the ceramic tile; 2. The construction is complicated, and th...
