    摘要： β-ZrNCl polycrystalline powder prepared by chemical transport method and NH 4 Cl are mixed in a molar ratio of 1:2. The mixture is encapsulated in a Au capsule (6 mm in inner diameter and 6 mm in depth) of a reaction vessel 2, which is then enclosed in a highly heat-conductivitive sodium chloride block as an electrically insulating pressure medium 6. The mixture held in the sodium chloride block is placed in a carbon tube 8 for serving as a heater. In a cubic-pressing apparatus using a pyrophyllite 12 as a pressure-transmitting medium, the mixture is heated at 900 °C for 2 hours under an applied pressure of 3 GPa. After the mixture is allowed to stand until it is cooled down to room temperature, the Au capsule is taken out and light green β-ZrNCl single crystals are obtained. A large single crystal among them had a hexagonal plate-like habit and is transparent with dimensions about 2 mm in diameter, and 0.3 mm in thickness.

    摘要： beta -ZrNCl polycrystalline powder produced by the chemical transport method and NH4Cl were mixed at a mole ratio of 1 : 2, the resultant mixture was placed in an Au capsule (6 mm of inner diameter, 6 mm of depth) as a reaction vessel (2) and the capsule was enveloped by a table salt block having a high thermal conductivity as an electrically insulating pressure medium (6). The reaction vessel was housed, together with the table salt block, inside the carbon tubes (8) as a heater and was heated under a pressure of 3 Gpa at a temperature of 900 DEG for 2 hr using a pyrophyllite (12) as a pressure transmitting medium by means of a hexahedral pressuring apparatus. After the vessel was allowed to stand for cooling to room temperature, the Au capsule was taken out, to give a light green single crystal of ss-ZrNCl. A large single crystal was a hexagonal, transparent plate having a diameter of about 2 mm and a thickness of 0.3 mm, which reflected the structure thereof.
