Embodiment 1
[0033] According to the proportion of ceramic raw materials (clay) accounting for 90% of the weight of the mixture, conductive filler particles with a particle size of 5μ-10μ accounting for 10% of the weight of the mixture, the mixture is composed, and the traditional manufacturing methods such as mixing, ball milling, granulation, molding, sintering, and glazing are used. The outer surface is insulated, and the ceramic tube with conductive strips embedded in the middle is made by pottery technology.
Embodiment 2
[0035] The mixture is composed of clay accounting for 50% of the weight of the mixture and conductive filler particles with a particle size of 50μ accounting for 50% of the weight of the mixture. After a traditional sintering process, a ceramic tube with an insulating outer surface and a conductive strip embedded in the middle is prepared.
Embodiment 3
[0037] The mixture is composed of clay accounting for 75% of the weight of the mixture, and conductive filler particles with a particle size of 30μ accounting for 25% of the weight of the mixture. After a traditional sintering process, a ceramic tube with an insulating outer surface and a conductive strip embedded in the middle is prepared.
