Abstract
This study explored the characteristics of TiB2 powders as an additive fuel of energetic materials. Results revealed that the whole oxidation of TiB2 was divided into two stages before and after the melting of B2O3. The effect of Ti on the onset oxidation temperature and low-temperature oxidation efficiency of TiB2 highlighted energy output features. The mass gain of the first stage, the combustion heat, the peak pressure, and the maximum pressurization rates of nano-sized TiB2 were larger than those of micro-sized TiB2. These properties of TiB2 provide evidence for the synergistic effect between Ti and B, which could promote its application in energetic formulations.
