FIELD: ceramics.
SUBSTANCE: invention relates to the production of high-density ceramics based on tetragonal Zirconium dioxide. Ceramic material contains an additive of lithium niobate in an amount of 2–5 % by weight, forming a low-temperature melt. Obtained material is characterized by a nanocrystalline structure and high mechanical characteristics: bending strength not less than 500 MPa. Developed materials can be used for the production of wear-resistant products, cutting tools, ceramic bearings, medical non-resorbable implants.
EFFECT: increasing the strength of materials sintered to a dense state at a low temperature of 1,300–1,350 °C.
