LOW-TEMPERATURE CERAMIC MATERIAL FOR THERMALY STABLE CAPACITORS Russian patent published in 1995 - IPC

FIELD: radio electronics. SUBSTANCE: improved stability of characteristics under heat and electric effects is achieved by inclusion into low-temperature ceramic material for thermally stable capacitors of barium titanate 89.75-95.52; niobium pentoxide 0.77-1.38, cobalt oxide 0.15-0.32; neodimium oxide 0.05-0.46; manganese dioxide 0.01-0.09; glass frit 3.50-8.00 per cent by mass. EFFECT: manufacture of material having dielectric permittivity 2200-2400, value of relative change of fielectric permittivity under effect of electric field having intensity E=2 kV/mm within temperature interval from -55 up to +125 C. 1 tbl
