| ABSTRACT |
|
This study has been undertaken with objective of studying the mechanism and condition of formation of hexagonal boron nitride from reduction of boric okide in the presence of carbon under nitrogen atmosphere. It was found that the formation of hexagonal boron nitride was started at 1400$^{circ}C$ and almost completed its conversion at 1550$^{circ}C$. The morphology of boron nitride synthesized in this study was very fine and platelet. It was considered as reaction pathway of hexagonal boron nitride that boron oxide was reduced to born and evaporated by activated carbon, and then it was reacted with nitrogen. |
