COMPOSITE CERAMIC MATERIAL Russian patent published in 2024 - IPC C04B35/50 

FIELD: chemistry.

SUBSTANCE: invention relates to production of ceramic ferroelectric composite materials and can be used in the electronic industry in the manufacture of a wide class of electric field-controlled elements and devices of electronic equipment. Proposed is a composite ceramic material containing strontium titanate and a complex lanthanum oxide of the composition La_1.8Ca_0.2Ni_0.8Cu_0.2O₄ at following ratio of components, mol.%: La_1.8Ca_0.2Ni_0.8Cu_0.2O₄ 93–99, SrTiO₃ 1–7.

EFFECT: obtaining complex lanthanum oxide with stable values of dielectric permeability in a wide frequency range, which provides a high level of dielectric permeability in the composition of the composite material and low dielectric losses.
