METHOD OF PRODUCING CERAMIC TEMPERATURE REFERENCE BASED ON ZnNiFeO FERRITES OF VARIABLE COMPOSITION Russian patent published in 2024 - IPC H01F1/10 H01F1/34 H01Q17/00 

FIELD: ceramics.

SUBSTANCE: invention relates to production of ceramic oxide materials and making elements of complex shape with given properties and can be used in devices of self-calibrating temperature sensors as a temperature element, as well as in electronics to expand the field of their application. Method of producing ceramic temperature reference based on Zn_1−xNi_xFe₂O₄ ferrites of variable composition, where the initial raw material for producing ferrites, the synthesis of which is carried out by a solid-phase reaction, are oxides of nickel, zinc and iron (III). Oxides are ground for 20 minutes, then the mixture is pressed under pressure of 30 kg/mm². Produced pellet is subjected to synthesizing firing at temperature of 1,400 °C for 5 hours, adding 5 wt.% paraffin, as well as gasoline, heating to 100–150 °C until complete dissolution of paraffin. Article is sintered at temperature of 1,400 °C for an hour.

EFFECT: invention enables to obtain ferrite ceramics in the form of a monolithic article of complex geometric shape with high magnetic permeability.
