Bulk modulus and P- V relationship up to 52 GPa of neptunium metal at room temperature
Abstract
High purity neptunium metal was studied under high pressure using a diamond anvil cell in an energy dispersive X-ray facility. No phase transition was observed up to 52 GPa. A bulk modulus B0 = 118 GPa and its pressure derivative B' 0 = 6.6. were calculated by fitting the V( P) data to the Birch and Murnaghan equations. The results are discussed in the context of recent compressibility measurements of other actinides.
