Abstract

The thermal coefficient of linear expansion (TCLE) was investigated in the course of heating and cooling in the temperature range between 200 and 1500 °C for the ceramic
materials based on Al2O3‒ZrO2 system. The influence of both the structure phase components and temperature conditions (heating/cooling) on the Δl/L = f(Т) dependences was defined, the dependence of the TCLE on the composite's chemical composition was described. The results obtained were discussed from the point of view of both the material phase composition and the literature data analysis. The data on the TCLE average and intrinsic values are given in the article. Ill. 3. Ref. 9. Tab. 2.

Keywords
