ORGANOMETALLIC FRAME MATERIAL AND METHOD OF PRODUCING ZIRCONIUM OXIDE DOPED WITH SCANDIUM USING SAME Russian patent published in 2025 - IPC C01G25/02 C22B34/14 C01F17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry and chemical engineering, specifically to synthetic chemistry of organometallic coordination materials based on zirconium salts and carboxylic acids, as well as to production of ZrO₂ doped with scandium. Zirconium carboxylates belong to the class of organometallic frameworks and are used as catalysts for various chemical processes, for obtaining metal-containing polymers, ceramic materials in microelectronics, solar power engineering, for production and accumulation of energy. Scandium-doped zirconium formate-based organometallic frame material having a composition ZrO(HCOO)₂⋅2H₂O : xSc³⁺ (x=0.025–0.1 at.%). Obtaining zirconium oxide, doped with scandium, involves annealing an organometallic frame material based on zirconium formate, doped with scandium, ZrO(HCOO)₂⋅2H₂O : xSc³⁺ (x=0.025–0.1 at.%) at temperature of 700-750 °C for 1-2 hours.

EFFECT: as a result of the invention, an environmentally friendly organometallic frame material based on zirconium formate is obtained, and also enables to obtain zirconium oxide using the obtained material.
