FIELD: chemistry.
SUBSTANCE: invention relates to making refractory and ceramic articles based on zircon dioxide and can be used mechanical engineering, aviation, petrochemical and electrical engineering. The mixture for producing ceramic material based on zirconium dioxide nanopowder contains the following in wt %: zirconium dioxide ZrO2 75-82 and a concentrate of rare-earth elements 18-25. The concentrate contains rare-earth elements (mainly cerium, lanthanum, praseodymium) in form of carbonates.
EFFECT: invention enables to obtain material at a lower cost by using a concentrate of rare-earth elements as a stabilising additive.
