Incorporation of Cadmium into Hexagonal Boron Nitride by Solid State Reaction

Abstract

In this study, cadmium-hexagonal boron nitride (Cd-h-BN) were synthesized according to the O’Connor method with varying amounts of cadmium(II) nitrate. The structural characterizations were performed with FTIR, XRD, and SEM techniques while the cadmium contents in Cd-h-BN were determined by AAS. XRD results shown that an increase in interlayer distance of h-BN, and nano-scale products were observed at 1050°C. The lattice constants were calculated by Scherrer equation and results were very close to the original h-BN. Although different amounts of Cd(NO3)2·5H2O were added in the starting mixtures, the cadmium contents of Cd-h-BN samples showed no significant difference and few amounts of cadmium was intercalated to h-BN. In addition, increasing cadmium amount caused to minor grain growth of h-BN samples.
