Polycrystalline Alumina — Thermal Expansion

Presented in the figure is a comparison of three test runs (lines) on a polycrystalline alumina (aluminum oxide) with the corresponding literature values (crosses) between room temperature and 1575°C. No visible deviations exist between the individual curves. Evaluation of the thermal expansion values at 500°C, 1000°C and 1500°C clearly shows that the measurement results are within 1% of the corresponding literature values. This test proves the outstanding reproducibility and accuracy of the dilatometer. (measurement with DIL 402 PC)
