摘要
立方氮化硼(CBN)是B与N形成的金刚石结构物质,它在自然界中还没有找到天然矿物。通常是在水、尿素和碱金属、碱土金属及它们的氮化物、硼化物、硼氮化物和合金等触媒参与,在高压高温条件下由六方氮化硼(hBN)转变而成的。同时一些添加物例如:Si、卤化物、P、B2O3、AlN、VB族等价杂质和尿素等对hBN转变为cBN也会产生重要的影响。此外,原材料的创新研究与组装方式的改进也有很大进展。本文就立方氮化硼的高压合成研究方面进行了综述。
Cubic boron nitride （CBN） is transformed from hexagonal boron nitride （hBN） under high pressure and high temperature with the occurrence of the catalyst such as the water, urea and alkali metals, alkali-earth metals and their nitrides, boride and boron nitride etc. Meanwhile, some additives such as： Si, halides, P, 13203, AlN, VB family equivalent of impurities and urea there will be an important impact. In addition, the irmovation of raw materials and improvement assembly mode has been made in the study. A brief summary was made in the article about Synthesis of Cubic Boron Nitride.
