Abstract

INVESTIGATION OF REFINING TECHNIQUE IN ULTRA-HIGH PURITY GE FOR PHARMACEUTICAL USE

Heredia Allex, Zemfira Kharitonova, Lukas Von, Henning Ström and Alex Leonardo

Abstract

A numerous research has been performed to optimize the parameters of zone refining process such as length, travel rate, number of passes and molten zone effect in high purification of germanium. Profiling of the impurity concentration along the zone refined germanium is established by several techniques. Due to the optimized parameters identified through the previous study, 7N (99.99999% purity) germanium is subjected to high purity zone refining for 49 passes and stirred at 30 rpm in our three-dimensional freezing system. The high purity zone refined germanium has a purity level of 8N (99.999999%) and the concentration of impurity is decreased to
