Research output: Contribution to journalJournal articleResearchpeer-review


The bulk modulus and thermal expansion of Zn3P2 has been investigated at pressures up to 21GPa and temperatures down to 100K. The experimental zero-pressure bulk modulus is 80.7 ± 1.8GPa, in accordance with the bulk modulus scaling and lattice properties of the related compound Cd3P2. A tetragonal to orthorhombic phase transformation occurs above 11GPa with a relative volume change of-7.1%. Values for the thermal expansion coefficient are reported at 293, 200 and 100K.
