Thermal expansion of Pb 3 O 4 was investigated by high‐temperature X‐ray diffraction. The coefficient in the a 0 direction is 14.6×10 −6 /°C. Expansion in the c 0 direction is 32% greater, with a coefficient of 19.3×10 −6 /°C. Coefficients of expansion are linear from 25° to 490°C and are comparable with those of tetragonal and orthorhombic PbO.
