Synthesis and characterization of boron nitride powder

The boron nitride powder is prepared from precursor sintering process and the boracic acid and melamine as raw materials. The effect of raw material ratio, reaction temperature, charging sequences in the synthesis process of precursor on total carbon content and boron-nitrogen mole ratio in precurso...

description	The boron nitride powder is prepared from precursor sintering process and the boracic acid and melamine as raw materials. The effect of raw material ratio, reaction temperature, charging sequences in the synthesis process of precursor on total carbon content and boron-nitrogen mole ratio in precursors is studied. The synthesis condition with 2:1 raw material ratio and 90°C synthesis temperature is determined, and determine to synthesize a precursor with a new structure by XRD, IR spectrogram characterization. The effect of sintering temperature and sintering atmosphere on the each component content in the high-heat treatment process is further studied; the technological conditions of preparation process are optimized, the heat treatment temperature is screened as the main factor to control the content of boron trioxide, thus, boron nitride powders with different purity are manufactured.
