Abstract

Single crystal growth of PdGa which is a highly selective catalyst forthe semi-hydrogenation of acetylene is reported for the first time.Bridgman as well as Czochralski methods were used starting fromoff-stoichiometric or congruent melting compositions. While Bridgmangrowth always resulted in poly-crystalline ingots with individual grainsrestricted to a few millimeters in size, using the Czochralski techniquefrom Ga-rich solutions allowed the growth of PdGa single crystals ofseveral cubic centimeters.
