摘要

摘要: 利用球磨法制备石墨-六角氮化硼微晶混合物，并在6.1 GPa、800~1 500 ℃条件下与水进行高压反应，以便研究用水作触媒合成B-C-N三元化合物的可能性。通过对反应产物的XRD、XPS谱分析发现：高压下随着温度的升高，反应产物中出现再结晶石墨，其晶化程度逐渐提高；但没有出现再结晶六角氮化硼，也未出现立方氮化硼。在球磨不充分条件下，石墨-六角氮化硼混合物的XRD谱没有完全弥散，它们与水高压反应时，能观察到石墨与立方氮化硼分别结晶的现象，但都没有形成B-C-N晶化结构。

Abstract: In this paper, the possibility of synthesizing the boron-carbon-nitride (B-C-N) compound by water catalyst has been investigated. The micro-crystal mixture of graphite and hexagonal boron nitride (hBN) was obtained by ball-milling. Under the temperature of 800~1 500 ℃ and the pressure of 6.1 GPa, this mixture reacted with water. By XRD and XPS, we analyzed the reaction products of the mixture with water, and found that the recrystallizing graphite formed and the crystallinity of graphite increased gradually when temperature increased, but recrystallizing hexagonal boron nitride (hBN) and cubic boron nitride (cBN) were not found. When the ball-milling was not sufficient, the XRD spectra peak of the micro-crystal mixture of graphite and hexagonal boron nitride (hBN) had not been widened sufficiently. The crystal of graphite and cubic boron nitride (cBN) were found, but the B-C-N crystal was not found.
