DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Partially crystd. lead-free and cadmium-free titanium bismuth silicate glass enamel compns. able to be fused at low temps. form predominantly bismuth titanate and optionally zinc titanate crystals upon firing. The glass enamel compns. include a glass component comprising, by wt.%, ~11~52% SiO2, 10.2~40% TiO2, ~5~75% Bi2O3, 0~8% B2O3, 0~14% BaO+SrO and 0~45% ZnO with (Bi2O3+ZnO) is ~30~85 wt.% of the glass compn. .

APPLICATION: EP 86-400997 9 May 1986.There are some reagents with their cas registry numbers 12047-27-7 and 12048-51-0 are used in this study. PRIORITY: FR 85-7198 13 May 1985. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Section cross-reference(s): 76 A layered ceramic component with radiation-shielding properties consists of a sintered block of layers of a 1st material, e.g., BaTiO3 contg. 20 wt.% BiTi2O7, contg. a high proportion of heavy atoms and provided on 31 surface with a layer of glass contg. only lightwt. atoms. The glass may have compn. SiO2 45-55, BaO 10-15, Al2O3 8-12, NaO2 5-10, B2O3 7-15, SrO 5-8, CaO 1-4, P2O5 0.5-2, and K2O 0.1-1%, with no PbO or Bi2O3, and the compns. are chosen so that the sintering temp. of the ceramic is higher than the m.p. of the glass, and to give compatible properties, e.g., thermal expansion. The glass is applied as a paste and vitrified with formation of an interdiffusion layer between the ceramic and the glass to insure good bonding. The component may include metallic regions, e.g., electrodes, of, e.g., Pt-Pd-Au alloy. .
