六方氮化硼的合成及表征
|
摘要
以硼酸、三聚氰胺为原料,通过高温反应,在氮气气氛下制备出六方氮化硼(h-BN)样品。考察了硼酸与三聚氰胺物质的量比、焙烧温度对h-BN产率、纯度及形貌的影响。制备h-BN最佳工艺条件:硼酸与三聚氰胺物质的量比为4.0∶1,1 000℃焙烧2 h,1 400℃焙烧2 h。在此条件下h-BN产率为25%、纯度为97%、粒度约为250 nm。
H-BN was prepared at high temperature under N2 atmosphere using boracic acid and melamine as raw materials.The effects of amount of substance ratio of boracic acid to melamine,and roasting temperature on h-BN yield,purity and morphology were studied.The results showed that the optimum technological conditions for the synthesis of h-BN were: amount of substance ratio of boracic acid to melamine of 4.0∶1,treated at 1 000 ℃ for 2 h and heated to 1 400 ℃ for 2 h.Under the above conditions,the yield of h-BN was about 25%,the purity reached 97%,and particle size was 250 nm.
