Formation of kaolin refractories heated in different gaseous atmospheres

Investigations of refractories made from Polozhe and Novoselits kaolins and fired in oxidizing and reducing conditions showed that development of the properties and phase composition occurs during heating to a certain temperature, in the process of soaking and cooling to 1200°C. The properties of kaolin refractories and their phase composition depend on the atmosphere, the firing temperature, soaking, and cooling rate. These factors are the main means of regulating the properties of refractories.
