ABSTRACT New and improved compacted or powder pressed materials for thermoelectric applications include a body formed from compacted power material in- cluding at least bismuth and tellurium and at least one highly electrically conductive phase. The materials are made in accordance with the general method of the present invention by forming a particulate mixture containing the constituent elements of a first compound including at least bismuth and tellurium and the constituent elements of a second compound capable of forming at least one highly electrically conductive phase, and thereafter, compressing at least a portion of said particulate mixture to form a compacted body of the material. In accordance with a first preferred embodi- ment, the first and second compounds are first separately prepared from their respective constit- uent elements. The first and second compounds are then combined and heated to form a melt. There- after, the melt is cooled to solid material form and then crushed to form the particulate mixture. In accordance with a second preferred embodi- ment, a melt is first formed from the second com- pound and the constituent elements of the first compound. The melt is then cooled to solid mate- rial form and then crushed to form the particulate mixture. In accordance with a further embodiment of the present invention, the first and second com- pounds are first separately prepared from their respective constituent elements and then separate- ly crushed into particulate form prior to forming the particulate mixture.
