The change in LTEC is analyzed on heating and cooling ceramic materials of the Al2O3–ZrO2 system in the range 200 – 1500°C. The effect of structural and phase components and measurement regime (heating/cooling) on form of the relationship Δl/l 0 = f(t), and also the dependence of LTEC on composite chemical composition are established. Results obtained are discussed from the point of view of material phase composition and published data are analyzed. Data are provided for average and true LTEC values.
