Abstract

An insulating composition comprises a mixture of finely divided mica and a low melting binder which consists principally of metal borates. The composition may comprise 10-60 per cent. titanium compound, 10-50 per cent. mica and 30-40 per cent. frit, the frit being either a lead borate composition, or a mixture of lead borate with borates of alkali and alkali earth metals, and may contain other constituents such as cryolite. These compositions are described in Specification 591,551. Alternatively the composition may be one of those described in Specification 588,650, and consist of powdered mica and a frit comprising 7-13 per cent. cryolite, 4-6 per cent. barium carbonate, 3-6 per cent. sodium carbonate, 5-8 per cent. potassium carbonate, 36-41 per cent. boric acid and 26-45 per cent. lead oxide.
