抄録

Morphologies of ice IV crystals were observed and their melting pressure (P) -temperature (T) relations were determined in a hydrothermal diamond-anvil cell at pressures up to 1 GPa. Water sample and a chip of BaTiO₃ were sealed in the sample chamber of the cell, and were observed under a microscope during isochoric cooling-heating cycles. Images of the sample, together with time and T, information, were recorded continuously on VCR tapes. The tetragonal to cubic phase transition in BaTiO₃ observed in heating was used to provide pressure and water density information for the sample. Our ice IV melting P-T data are in excellent agreement with those predicted by the equation formulated previously based on the data collected at pressures between 0. 4 and 0. 6 GPa.
