Since the low-pressure diamond deposition was discovered in 1982 there is a high interest to find a similar process for the c-BN synthesis. During the last years many researchers propagated success, but many of them failed in analytical problems characterizing the BN coatings. However new papers by S. Matsumoto and W. Zhang show c-BN deposition using a DC Plasma Jet and characterization by various analytical methods. In order to investigate the possibility to deposit c-BN in a pure chemical vapor deposition (CVD) process, we carried out experiments with a simple CVD reactor without plasma activation. Various BN layers were deposited and characterized. X-ray diffraction, IR-spectroscopy and SIMS indicate that BN-coatings containing c-BN were deposited. However, a final verification of c-BN crystallites by TEM investigations was not possible till now.
