Abstract

801,570. Glass. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 25, 1957 [Feb. 17, 1956], No. 5028/56. Class 56. Semi-conducting glasses capable of being formed into thin film comprise, in weights per cent (with a particular example in brackets) : BaO 10-50 (50); P2O5 30-70 (35); V2O5 10-30 (15). Any other ingredients consist of one or more of Na2O, CaO, SrO, MgO, B2O3, Al2O3 and TeO2 but are restricted to a total of 5 per cent except in the case of Na2O (which may result from the commercial source of the P 2 O 5 ).Less than 1 per cent of unavoidable impurities may also be present.
