Abstract

High pressure synchrotron x-ray diffraction experiments were conducted on KCa 2Nb 3O 10, to determine lattice constants as a function of pressure. A diamond anvil cell was used to produce pressures up to 66 GPa. A phase transition occurred at 13.5 GPa. From the lattice constants, linear compressibilities of 8.55×10 -4 GPa -1 in the a direction, -9.40×10 -4 GPa -1 in the b direction, and 142×10 -4 GPa -1 in the c direction, and a bulk modulus of 68.5 GPa were found for the lower pressure orthorhombic phase.
