稳定性 | 常温常压下稳定 避免光,明火,高温。与石墨性质相似,有良好的电绝缘性、导热性和耐化学腐蚀性。抗氧化性能甚强,在高温时也具有良好的润滑性,是一种优良的高温固体润滑剂。具有很强的中子吸收能力。化学性质稳定,对几乎所有的熔融金属都呈化学惰性。氮化硼不溶于冷水,与水煮沸时水解非常缓慢,产生少量硼酸和氨。与弱酸和强碱在室温时均不起反应,微溶于热酸,用熔融的氢氧化钾处理方能分解,氯气也只能在赤热的条件下方与它起反应。能耐高温至2000 ℃。具备便于机械加工的优良性能。立方晶型氮化硼硬度与金刚石相当,在1500~1600 ℃高温中稳定性优于金刚石。 氮化硼纤维:属多晶BN纤维。熔点300℃;直径4~6μm;密度1.8~1.9g/cm3;强度约2GPa;模量340~350GPa。氮化硼纤维与某些无机纤维相比,具有耐高温、耐化学腐蚀、电热性能好、耐辐射等优良特性。它的抗氧化温度比碳纤维、硼纤维的高,在惰性条件下,2500℃以上仍保持稳定;在氧化气氛中,850℃仍是稳定的。 六方晶系结晶。用高压高温处理所制得的是立方晶系结晶。六方晶系氮化硼的晶体结构和物理性质类似于石墨(但具有电绝缘性)。也称白石墨(white graphite)。莫氏硬度为2,具有优越的润滑性。在氧化气氛中约800℃,在惰性气体气氛中约3000℃是稳定的。不被熔融金属和矿渣所润湿。电绝缘性好,无毒,立方晶系氮化硼具有比金刚石还强的硬度。 |
储存条件 | 氮化硼贮存方法:应贮存在通风良好的干燥库房内,防止受潮。 氮化硼纤维贮存方法:贮存于通风良好、干燥库房内。空气中允许氮化硼最高浓度为6mg/m3。 |
