Single crystal of the orthorhombic perovskite modification of MgSiO 3 have been grown from a melt at 27 GPa and 1830°C. The starting material of orthoenstatite was sealed in a platinum capsule with water. Crystals of good quality up to 200 microns in size were obtained, which are promising for the structural refinement, Brillouin spectroscopy, and other measurements. Some crystals, however, exihibit twinning on the (110) plane.
