Combustion Synthesis Reaction

Micro-nanoTiB2 ceramic was prepared through increasing the molar ratio of Mg and leaching with suitable acid by the combustion synthesis reaction of Mg, TiO2 and B2O3, which could get higher temperature and purer product. The Samples were investigated by XRD and SEM, and the results showed the diameter of the TiB2 was 200 nm ~ 300 nm and the shape of the TiB2 was irregular hexagonal crystal. The diameter of the TiB2 was decreased with the increase of Mg powder. The formation mechanism of TiB2 has been studied.

Since 1990, Ge and his earlier and present groups in LSCPM have made great efforts to investigate the Self-propagating High-temperature Synthesis (SHS) of Si-N2 gas-solid system including the SHS process control and its thermodynamics, structural macrokinetics and formation mechanism of SHS-Si3N4. In this presentation, some results that were firstly reported in the world are reviewed and new progress in recent years is reported.
