Three systems of glass ceramics with different chemical compositions were prepared by high gravity combustion synthesis. Most samples were dense with a low porosity, which can be attributed to accelerated separation and removal of gas bubbles from ceramic melts in a high gravity field. The hardness of the as prepared glass ceramics varied in the range of 8·2–12·8 GPa and could be improved by a fine eutectic structure. Compared with conventional techniques, high gravity combustion synthesis can offer a fast and efficient way to prepare glass ceramic materials.
