                  氮化硼的物質結構

                  氮化硼的物質結構

                  氮化硼的物質結構

                    氮化硼六方晶系結晶,最常見為石墨晶格,也有無定形變體,除了六方晶型以外,碳化硼還有其他晶型,包括:菱方氮化硼(簡稱:r—BN,或稱:三方氮化硼,其結構類似于h—BN,會在h—BN轉化為c—BN的過程中產生)、立方氮化硼[簡稱:c—BN,或|3一BN,或z-BN(即閃鋅礦型氮化硼),質地非常堅硬]、纖鋅礦型氮化硼(簡稱:w—BN,h—BN高壓下的一種堅硬狀態)。人們甚至還發現像石墨稀一樣的二維氮化硼晶體(類似的還有MoS:二維晶體)。
