Abstract

1285380 Ceramics MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 22 Oct 1969 [8 Nov 1968] 51695/69 Heading C1J A ceramic composition consists essentially (defined) of ZnO and 0À05-10 mole per cent of BaO. In addition, 0À05-8 mole per cent of CaO, CoO, PbO or SrO can be present; or 0À05-8 mole per cent of Bi 2 O 3 and 0À05-8 mole per cent of either SrO or PbO; or 0À05-8 mole per cent of PbO with 0À05-8 mole per cent. of either SrO or CoO.
