The influence of a burnable additive in the form of petroleum coke and brown coal on the properties of lightweight heat-insulating materials is considered. It is shown that the high ash content of coal and the increased content of low-melting oxides in the ash activates the sintering process. By the selection of fillers and clay binder, as well as the firing temperature, it is possible to obtain aluminosilicate light weights with an optimal combination of physical and technical properties, such as density, strength and thermal conductivity.
