Abstract
Flue gas- or filter-dust, having >=20 m2/g specific surface, is mixed, as SiO2- and metal oxide-contg. powder of high specific surface with ceramic raw materials, e.g. clay, followed by heating to sintering with simultaneous pore-formation. Products are expanded clays, useful as building and insulating materials, refractory linings for furnaces and for glass prodn.
