| 摘 要： | 详细考察了三氧化二硼在高温高压条件下的相变过程。研究结果表明，在高温高压条件下，三氧化二硼经历了从立方晶系向六方晶系、正交晶系和非晶相的相变。文中还比较详细地讨论了高温、高压两种因素对结构相变的影响，以及静高压熔态淬火方法在非晶态材料制备方面所具有的独到之处。

| Abstract: | This paper describes the transformations of boron oxide B2O3 under high pressure and high temperature. We have found that boron oxide B2O3 with cubic system is transformed into hexagonal and orthorhombic B2O3 under a pressure of 5.0 GPa and a temperature of 800 ℃. Under pressure of 4.0 GPa and temperature of 1000 ℃, cubic B2O3 is transformed into amorphous state, whose colour is white. Moreover, structural changes with increasing temperature and pressure, and method of quenching from a fusing state under high static pressure are discussed. |
