氮化硼具有类似的石墨层状结构，呈现松散、润滑、易吸潮、质轻等性状的白色粉末。 莫氏硬度为 2 ，化学性质极其稳定。产品具有很高的耐湿性，在氮或氩中使用，温度可达 2800 摄氏度。它不仅具有低的热膨胀系数，又有高的热传导率，既是热的良导体，又是典型的电的绝缘体。 金属成型的脱模剂和金属拉丝的润滑剂； 高温状态下的特殊电解，电阻材料； 固体润滑剂； 晶体管的热封干燥剂和塑料树脂等聚合物的添加剂； 压制成各种形状的氮化硼制品，可用做高温、高压、绝缘、散热部件； 航天航空业中的热屏蔽材料； 在触媒参与下，经高温高压处理可转化为坚硬如金刚石的立方氮化硼。 Hexagonal boron nitride (hBN) has a layered structure similar to graphite and can be exfoliated as singlelayered BN sheets. hBN has applications in catalysts, optoelectronics and semiconductor devices. Boron nitride posseses high thermal conductivity of approximately 400W/mK at 300K. Hexagonal boron nitride powder has been used: · In the fabrication and luminescence study of monolayered boron nitride quantum dots. · Rare earth boron complexes. · Boron nitride filled polybenzoxazine system as a thermally conducting molding components for electronic packaging applications. · Boron containing ceramic products. · As a starting material to form BN nanotubes. · To load silicone rubber and its consecutive effect on its thermal, mechanical and morphological properties was studied.
