Starting raw materials, clay and diatomite, from coal mine Kolubara, Serbia were purified using heat and chemical treatment. Porous silica ceramics were obtained at low forming pressure (40-80 MPa) and low sintering temperature (1000-1300 °C) in air. Boric acid as a /ow-cost additive was used. Sintered samples have average pore si:ze diameters ranging of macroporous for clay 0.1-10 μm and for diatomite 0.05-5 μm. As-received and the obtained samples were characterized by XRD, SEM and mercury porosimetry measurements. Relations between mechanical characteristics of samples formed at different temperature were studied.
