Singh, A J and Mathur, B S and Suryanarayana, P and Tripathi, S N (1969) Preparation of Electronics grade Bismuth, Antimony, Tellurium, Cadmium and Zinc by Vaccum distillation and Zone refining. In: Symposium on Non-ferrous Metals Technology. Symposium on Non-ferrous Metals Technology, Volume III - Nickel, Lead, Zinc, Rare earth and Nuclear Metals . NML, Jamshedpur, Jamshedpur, pp. 82-91.
APART from the usual importance of bismuth, antimony, tellurium, cadmium & zinc in thechemical, metallurgical, cosmetic, pharmaceutical and paint industries , these materials in their high purity forms (9999 to 99999 %) have recently acquired special significance in the electronics industry for semiconductor and various other applications. The major applications of these electronics grade materials in the electronic industry are : Bismuth : solders and thermo-electric devices, Antimony : semi-conductor devices + for crystal doping), photocell cathodes, Tellurium Compound semi-conductors Cadmium Solders mostly for semi-conductor processing and for compound semi-conductors, such as CdS. Zinc : dopant and diffusant in semi-conductors.
