Claim 1
Independent Claim
104 words
A PROCESS FOR PREPARING A THERMOELECTRIC ELEMENT COMPRISED OF A COMPACTED HOMOGENEOUS INTERMETALLIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF INDIUM ANTIMONIDE, INDIUM ARSENIDE, CADMIUM ANTIMONIDE AND ZINC ANTIMONIDE, COMPRISING, ADMIXING PREDETERMINED AMOUNTS OF TWO FINELY POWDERED METALS TO FORM AN INTERMETALLIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF INDIUM ANTIMONIDE, INDIUM ARSENIDE, CADMIUM ANTIMONIDE AND ZINC ANTIMONIDE, SINTERING THE ADMIXTURE IN AN INERT ATMOSPHERE AT A TEMPERATURE 20*C. TO 100*C. BELOW THE MELTING POINT OF THE INETERMETALLIC COMPOUND FOR FROM 2 TO 15 HOURS, AND COMPACTING THE SINTERED ADMIXTURE UNDER SUFFICIENT PRESSURE AND HEAT TO FORM A COMPACT OF DESIRED DENSITY AND CONFIGURATION.
