On fusing the ditelluride in the blowpipe flame and then allowing it to cool, platinum monotelluride crystallises out in polyhedra.
It may also be obtained by heating an intimate mixture of finely divided tellurium (100 parts) and platinum (150 parts) in a glass tube until combination takes place. The tube and its molten contents are now melted together and dropped into cold water. The telluride then yields quite good crystals. |
