Abstract
A crystal detector is made from highly purified germanium of not less than 99.95 per cent purity which is obtained by distilling the tetrachloride from hydrochloric acid in excess of chlorine. The tetrachloride is received in distilled water from which hydrated germanium hydroxide is recovered and dissolved in hydrochloric acid to repeat the process as often as is necessary. Finally, the pure germanium oxide is reduced with pure hydrogen and the resulting powder is fused in an inert atmosphere to form the solid metal which is broken into fragments to provide detector elements.
