The results of study of chemical and mineralogical composition and technological properties of basalts and tuffs, explored on the territory of the Republic of Belarus are presented, and the possibility of their use as components of ceramic materials for interior wall facing tiles is established. The criterion of intensification of the sintering process of raw compositions, expressed by ratio of oxides (SiO2+ Al2O3) / (Fe2O3+ FeO + Na2O + K2O), is defined and the limits of its values is set, at which open porosity of the tiles reduce to 16.0–21.5%, mechanical flexural strength up to 35.0–36.5 MPa, water absorption value is 13.2–9.8%, shrinkage – 1.2–1.3%, thermal coefficient of linearexpansion (TCLE) – (6.87–7.05) · 10 –6 K –1
