摘要： 以石墨和六方氮化硼(h-BN)粉为原料,利用高能机械球磨和高温高压技术对BCN化合物的形成、结构及相变进行了研究.经120h球磨制备出BCN非晶体.在1400cm-1附近,BCN非晶有一宽化的强红外吸收峰,在740和1630cm-1附近观察到弱的红外吸收峰;在1330cm-1附近观察到一宽化的Raman散射峰.BCN非晶中B1s的结合能为191.9eV,C1s的结合能为284.9和286.8eV,N1s的结合能为398.3和400.5eV.将BCN非晶在4GPa和1473K下退火45min后转化为六方结构的BCN晶体,其晶格常数为a=0.2505nm,c=0.6664nm.其红外光谱特征吸收峰分别出现在1398,1103,1024,925和802cm-1.Raman散射峰分别出现在1328,1358,1582和1614cm-1.并对非晶BCN的形成和相转变机制进行了研究.

Abstract: Formation, structure and phase transition of BCN compound were investigated by mechanical milling of mixture of graphite and hexagonal boron nitride or annealing the as-milled mixture at high temperature and high pressure. Amorphous BCN(a-BCN) was prepared by milling the mixture for 120 h. A broad and strong absorbed peak locating at 1 400 cm-1 and two weak peaks locating at 740 and 1 630 cm-1 respectively were observed in the infrared spectrum of the a-BCN, and a broad (Raman) scattering peak was found at 1 330 cm-1 in its Raman spectrum. The binding energies of the (a-BCN) are 191.9 eV for B1s, 284.9 and 286.8 eV for C1s, 398.3 and 400.5 eV for N1s, respectively. (A hexagonal) BCN(h-BCN) with lattice constants of a=0.250 5 nm, c=0. 666 4 nm was produced by annealing the a-BCN for 45 min at 1 473 K and 4 GPa. Its infrared absorbed peaks appeared at 1 398, 1 103, 1 024, 925 and 802 cm-1, respectively, and Raman scattering peaks are observed at 1 328, (1 358), 1 582 and 1 614 cm-1, respectively. The mechanisms of the formation and phase transition of the BCN compound are discussed.
