Abstract

We determined the equation of state for ammonium fluoroberyllate up to 3 GPa in the temperature range from 160 to 300 K using energy dispersive X-ray diffraction. The bulk modulus and its pressure derivation at room temperature as well as the thermal expansion coefficient at 640 MPa were obtained from these measurements. Our results indicate that the bulk modulus and its pressure derivative have a negligible temperature dependence in this temperature range.
