Description
氮化硼具有抗化学侵蚀性质，不被无机酸和水侵蚀。在热浓碱中硼氮键被断开。1200℃以上开始在空气中氧化。真空时约2700℃开始分解。微溶于热酸，不溶于冷水，相对密度2.29。压缩强度为170MPa。在氧化气氛下最高使用温度为900℃，而在非活性还原气氛下可达2800℃，但在常温下润滑性能较差。氮化硼的大部分性能比碳素材料更优。对于六方氮化硼：摩擦系数很低、高温稳定性很好、耐热震性很好、强度很高、导热系数很高、膨胀系数较低、电阻率很大、耐腐蚀、可透微波或透红外线。
氮化硼六方晶系结晶，最常见为石墨晶格，也有无定形变体，除了六方晶型以外，氮化硼还有其他晶型，包括：菱方氮化硼（r-BN)、立方氮化硼（c-BN）、纤锌矿型氮化硼（w-BN)。人们甚至还发现像石墨稀一样的二维氮化硼晶体。
