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。

1.三氯化硼氨气气相沉积法 将制得的三氯化硼和氢气一起同加热到一定温度的氨气充分混合,在规定要求的反应温度下于反应器中进行反应,然后再在较高的温度下,在氨气流中继续加热一定时间,制得氮化硼成品。其反应方程式如下:

10043-11-5 preparation

2.硼砂氯化铵法 将硼砂在450℃和压力79993 Pa下进行脱水,氯化铵预先在110~120℃下烘干,分别粉碎到40目细度。按无水硼砂和氯化铵质量比为1:0.59进行配料,混合并加压成型。然后,送人反应炉中,并通入过量的氨,在1050℃下进行反应,生成氮化硼粗晶,经粉碎、过筛、水洗、过滤、干燥后,制得氮化硼成品。其反应方程式如下:

10043-11-5 preparation

立方晶型氮化硼的制造,可用六方晶体做原料,加入镁粉,在氢化锂粉添加剂参加下,在高压高温下进行反应制得。

3.硼酸法由硼酸与磷酸三钙等在氨气中加热制得。

氮化硼纤维制法:由氧化硼熔融纺丝得到三氧化二硼纤维,然后在350℃以上温度下在氨气中加热形成硼胺,再于1800℃氨中进一步高温烧结得到纯纤维。若要得到复合纤维,则需以硼烷、氨、氯化硼为反应气,在炽热钨丝上进行化学气相沉积即可。或者首先合成硼氮环高分子,再于100℃左右对其进行熔融纺丝。纺丝后在氨气中烧结,1000℃时纤维呈黑色,如果在氨气中进一步烧结,温度1200℃时为棕色,1400℃时为白色。

4.工业上较好的制法是用三氧化二硼或者硼酸盐与含氮化合物进行反应(800~1200℃)。用这种方法制成的产品中,残留有少量未反应原料。在实验室中为得到少量纯度高的氮化硼,可利用卤化硼和氨反应来制取。

5.在不断通入干燥氢气的过量液氨中,慢慢滴加BBr3(熔点-45℃)。将氨蒸发后,将白色残渣(有吸湿性)在干燥的氨气流中慢慢地加热到750℃,则制得白色氮化硼。或者,使BCl3(沸点12.7℃)和氢气的混合气与过量氨在600~1000℃下混合反应。产物再在氨气流中于1000℃下加热1h。

6. 无机先躯体转化法 将三氧化二硼熔融纺丝制成B2O3纤维,然后在350℃以上温度下,用氨气氮化,再进一步高温烧结而得。该法不易制得连续纤维,其分散性较大。
7.有机先躯体转化法 可选的有机先躯体很多,如B.B.B三甲氨基环硼氮烷在10%的十二烷基胺存在下进行热缩合,制得硼氮杂环大分子,在100℃左右进行熔融纺丝,在纺丝过程中,纤维表面由于轻微水解而不熔化,故可直接在氨气中烧结到1000℃,有机基团分解,纤维呈黑色,如果在氨气中进一步烧结,温度1200℃时为棕色,1400时为白色。
