Another method of densification makes use of reaction hot-pressing or self-propagating combustion sintering of MC-B powder mixtures under pressure ... 

Green samples or net shape articles should have the optimum initial porosity (0o)- On the one hand, 0q should be as small as possible, which makes it easy to produce pore-free material after combustion sintering. On the other hand, as shown above, Bq is one of the main parameters that defines the combustion regime and the degree of final conversion for example, too small Bq could make impossible to accomplish the steady-state combustion regime. 

The redispersion is carried out in order to increase the dispersion, after the metal sinters during the coke combustion. Sintering is favored mainly at high temperatures, and the presence of certain substances such as water, coke, and sulfur. As previously presented, the redispersion process consists of a treatment under an oxidizing atmosphere in the presence of chlorine. This step of the regeneration process may take 4 h approximately, at temperatures between 480 and 510°C.
