The in-flame crystallization of a metastable BN form

The aim of the present work was to investigate the in-oxygen-hydrogen-flame synthesis process of BN using a new source of boron and nitrogen, namely the borane-ammonia compound BH3 · NH3, and placing the flame in a strong electric field (6 × 105 V m−1). The metastable form of BN, E-BN, forms as result of an in-flame reaction. The yield of the E-BN synthesis is strongly affected by the presence of the electric field.
