Abstract

Structural change of β-tricalcium phosphate (β-TCP) was studied in situ by high-temperature neutron powder diffraction technique. Crystal structure was refined by Rietveld analysis of neutron diffraction data. The lattice parameters a, b and unit-cell volume V of β-TCP increased with an increase of temperature. Distortion from ideal structure decreased with increasing of temperature.
