• B-C-N
• Precursor spraying
• High purity

High purity microporous B-C-N ceramics have been successfully synthesized by precursor spraying route without the assistance of template and any other additives. Scanning electron microscopy (SEM) investigation indicated that the sizes of the pores in the ceramics were ranging from 5 to 20 mu m. Nitrogen adsorption measurements showed that the products had a surface area of 55 m(2) g(-1). X-ray photoelectron spectrometer (XPS) and TEM revealed that the main compositions of the products were graphite and hexagonal B-C-N ternary compound.
