Mixtures of bauxite and kaolin in various proportions were heated at temperatures up to 1500 °C in order to create porous ceramic materials for possible use in refractory applications. The physical properties of technological interest related to the possibility of using them in refractory applications are investigated. On this way the production of an open-porous mullitic material of an interesting combination of properties such as sufficient compressive strength as well as refractoriness under load is achieved.
