Monodispersed boron carbonitride hollow spheres with high-performance microwave absorption property
Source abstract
Abstract
Abstract A novel method, combining polymerization and pyrolysis of single precursor on graphite sheet, has been developed to synthesize monodispersed boron carbonitride hollow spheres in large-scale. The products have hollow architectures (2–3 μm in diameter) with nano-pores on the spherical walls and a composition of B 0.23 N 0.19 C 0.58. The products exhibit the minimum reflection loss of −42.5 dB at 12.6 GHz (the effective reflection values are obtained in a very wide range of 3.4–17.3 GHz) suggesting a new and high quality microwave absorbent.
