Abstract
1290856 Pyroelectric glass STANDARD TELEPHONES & CABLES Ltd 5 June 1970 [9 June 1969] 29063/69 Heading C1M A method of making a pyroelectric glass includes the step of cooling a glass from its glass transition temperature to at least 100 C. below its annealing temperature whilst maintaining it in an electric field of at least 100 volts per centimetre. The glass contains between 5 and 20 mole per cent in total of one or more glass modifying oxides chosen from Group IIa or IIb of the Periodic Table and preferably contains sodium and calcium ions. The glass may be coated on to a semi-conductor device, e.g. of silicon, before treating as above.
