FIELD: electrical industry.
SUBSTANCE: invention relates to ferroelectric materials and can be applied in the electrical industry for the production of multilayer ceramic capacitors. The character of the invention consists in a ferroelectric material containing barium titanate, oxides of niobium, manganese, lead, bismuth, zinc, titanium, silicon, boron, nickel, neodymium, tin, tungsten, molybdenum and aluminum, which are selected in appropriate concentrations.
EFFECT: invention enables to increase the dielectric constant of the ferroelectric material to 3400-3600 with a concomitant decrease in the magnitude of the tangent of the dielectric loss angle to 0.6–0.8% and the magnitude of the relative change in the dielectric constant in the operating temperature range to ± 15% at a sintering temperature of 1070-1130 °C.
