High pressure synchrotron x-ray diffraction experiments were conducted on KCa{sub 2}Nb{sub 3}O{sub 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 {times} 10{sup {minus}4} GPa{sup {minus}1} in the a direction, {minus}9.40 {times} 10{sup {minus}4} GPa{sup {minus}1} in the b direction, and 142 {times} 10{sup {minus}4} GPa{sup {minus}1} in the c direction, and a bulk modulus of 68.5 GPa were found for the lower pressure orthorhombic phase.
