The properties of porous TiO2TiC/C and TiC biomorphous materials

Purpose: Purpose of this paper is to present results of the ceramization of biomorphic materials under different conditions. The aim of the study is to characterize the structure and the usefulness of the material resulting in further applications. Possibility of making a porous material made up of different phases and composition depending of high temperature process and the input material has been demonstrated. Design/methodology/approach: Pyrolisis was done on wood pine samples. Obtained char was subjected to infiltration with solution of titanium alkoxide precursor. After the process of infiltration and drying ceramization subjected in carbon-TiO2 char in three different conditions. Scanning microscopy investigation and XRD analysis were carried out. Structure and phase composition of various biomorphic materials was determined and
