Preparation of TiC and SiC powders by self-combustion reaction

摘要

The present invention relates to TiO₂Or SiO₂And Mg and C were mixed at a constant molar ratio and compressed to a molding pressure of 500 psi and 3000 psi, respectively, to make pellets. The pellets were subjected to low-temperature ignition in an Ar atmosphere in an SHS reactor and then leached in HCI. And a method for producing SiC
