ABSTRACT:
The invention relates to a method of making a thermo-element having two sections with two electric conductor materials of different thermo-electric properties connected in series. The method involves forming a porous base body with interconnected pores and introducing p and n type conductor materials respectively into the pores of the two sections. The introduction of the two conductor materials involves forming one or two melts of molten silicon which travels through the body via a capillary action. Doping material is introduced in the melt material or directly into the body where it is picked up by the molten material which is subjected to the capillary action. The two conductor materials results by reason of the capillary action producing a reactive sintering between the graphite and the doped silicon melt.
