High Temperature Synthesis

Aluminum nitride was synthesized by self-propagating high-temperature synthesis (SHS) with flaky aluminum powder in various conditions such as particle size, nitrogen pressure (PN 2), dilution factor f( Dil</sub), packing density, and bulk sample size. AlN content in the SHS product increases with an increase of fDil, and it eventually reaches about 95 % at fDil=0.6. Generally, reaction front velocity is significantly affected by PN2 and packing density, but not by fDil. The degree of AlN conversion reduces more or less with an increase of bulk sample size, but that could be improved by using the SHS pre-prepared product as a diluent.

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.
