Abstract

A method for forming a densified solid object corresponding to a thermoelectric element from a mixture of uncompressed, powdered constituent materials. A powdered precursor material may be selected to cause a shrinkage of at least twenty percent in at least two mutually orthogonal linear dimensions of a densified solid object compared to corresponding dimensions of a mold cavity. In some embodiments, a precursor material is selected to produce a thermoelectric material having electrical and mechanical properties suitable for a thermoelectric module. In some embodiments, at least two thermoelectric elements are electrically connected to conductive plates to form a thermoelectric module.
