Boron carbide (B4C) is one of the hardest materials and therefore commonly used for a variety of applications including armor plating, blasting nozzles and mechanical seal faces, as well as for grinding and cutting tools. Conventional production methods of B4C, such as carbothermal reduction in industrial scale requires high investment and high operating costs, inhomogeneous resultant material, etc.
Zirconium diboride (ZrB2) is a highly covalent refractory ceramic material which is considered as an ultra-high temperature ceramic (UHTC) with a melting point of 3246 °C. ZrB2 with its relatively low density of ~6.09 g/cm3 and good high temperature strength has a potential to be used for high temperature aerospace applications.
In the present study, a method based on sulfuric acid dehydration of sugar was developed to synthesis a precursor material, which can yield B4C and in situ B4C/ ZrB2 composites at much lower temperatures compared to traditional carbothermal methods. The precursor material was heat treated at the temperatures between 1000 and 1600oC under inert atmosphere and characterized by XRD, SEM and FTIR.
