Synthesis of AgSbTe<SUB>2</SUB>/Ag<SUB>2</SUB>Te composite by mechanical alloying from elemental powders is described. Mechanical alloying was done by vibratory ball milling with a ball-to-powder ratio of 100:1. The studied composition range was Sb<SUB>2</SUB>Te<SUB>3</SUB>-xmol%Ag<SUB>2</SUB>Te (x=43-70); the (β+Ag<SUB>2</SUB>Te) region in the Sb<SUB>2</SUB>Te<SUB>3</SUB>-Ag<SUB>2</SUB>Te phase diagram. XRD analysis showed that after sufficient milling β compound AgSbTe<SUB>2</SUB> was found to be formed for x=43. The composites of various compositions were formed depending on the initial mixing ratios. The sintered compacts of the mechanically alloyed powders had homogeneous composite microstructures and exhibited the increase in the connectivity of the second phase Ag<SUB>2</SUB>Te in the AgSbTe<SUB>2</SUB> matrix with increase in the Ag<SUB>2</SUB>Te content.
