Abstract

Bismuth, antimony, tellurium, cadmium and zinc, in their ultra-high purity forms (99.99 to 99.999%), have recently acquired special significance in the electronics industry. Several methods such as precipitation, crysta-llization, electrolysis, distillation, ion-exchange, sol-vent extraction, zone melting, etc. are available for the preparation of such high purity and electronics grades materials
