Annealing effects on negative thermal expansion …

Ball mill processing diminishes the NTE properties of β-Cu 1.8 Zn 0.2 V 2 O 7. Annealing did not fully restore the NTE properties. However, for a sample annealed at 500 °C, the absolute value of the negative CTE was found to be greater than the crystallographic value, indicating that ball milling did not completely destroy the β-Cu 1.8 Zn 0.2 V 2 O 7 microstructure.
