Abstract Extrusion is a perspective forming technology for obtaining objects with certain profile. Nowadays it is widely used as ceramic materials forming technology - it is relatively cheap and productive. Titanium oxide can be used as biomaterial, photocatalyst, electrode in the electrolysis process etc. The aim of this work was to obtain dense titanium oxide ceramics using extrusion technology. During investigation extrusion mass preparation technology to obtain dense and qualitative samples was developed. Additives used to prepare extrusion mass were: water, plasticizer and binding agent. Green density of cylindrical samples after extrusion was in range from 52.4 to 53.4 % of theoretical density. Extruded samples were calcinated at 1100 °C and sintered at 1450 °C. Microstructure of obtained samples was investigated using scanning electron microscopy. During the investigation it was concluded that sample density is influenced not only by composition of raw materials but also by mass preparation and forming technology.
