Abstract

577,976. Silicon. GENERAL ELECTRIC CO., Ltd., RANSLEY, C. E., RYDE, J. W., and WILLIAMS, S. V. Dec. 19, 1941, Nos. 16431/41 and 12969/42. [Class 90] In the preparation of material for crystal contacts by melting silicon with small amount of additive material such as aluminium or beryllium and cooling slowly to form a solid product, the solid product is maintained for a considerable time at a temperature greatly above atmospheric temperature but below the melting point and is thereafter quenched rapidly. For example it may be maintained at 1,050‹C. for one hour. Specifications 577,181 and 589,592 are referred to.
