    摘要： β-ZrNCl polycrystalline powder prepared by chemical transport method and NH4Cl 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.

    摘要翻译： 通过化学转移法和NH 4 Cl制备的β-ZrNCl多晶粉末以1:2的摩尔比混合。 将混合物包封在反应容器2的Au胶囊（内径6mm，深度6mm）中，然后将其包封在作为电绝缘压力介质6的高导热性氯化钠块中。 将保持在氯化钠块中的混合物置于用作加热器的碳管8中。 在使用叶腊石12作为压力传递介质的立方压制装置中，将混合物在3GPa的施加压力下在900℃下加热2小时。 使混合物静置直至冷却至室温后，取出Au胶囊，得到浅绿色的β-ZrNCl单晶。 它们中的大单晶具有六角形板状习惯，并且是透明的，其直径大约为2mm，厚度为0.3mm。

    摘要： null-ZrNCl polycrystalline powder prepared by chemical transport method and NH4Cl 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 900null 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 null-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.
