摘要
Boron-rich solids are good candidates to apply instead of diamond. Boron has a unique crystal structure and compounds of it are resistant to heat treatment. These structures have light density, high hardness, and chemically inertness. Also, boron compounds display thermal and electronic properties as a thermoelectric power at high temperatures. A boron, carbon, nitrogen, and oxygen containing compound was synthesized for the first time by classical microwave method using elemental amorphous boron, active carbon, and urea with 1: 1: 1 molar ratio. The compound is crystallized in monoclinic system with unit cell parameters a = 12:9575 angstrom, b = 9:3264 angstrom, c = 9:6529 degrees, beta = 113:277 degrees which are calculated by POWD indexing program. The X-ray diffraction, POWD, the Fourier transform infrared, scanning electron microscopy/energy X-ray diffraction spectroscopy and thermogravimetric/different thermal analysis were achieved.
