TITANIUM CARBIDE (TiC), SYNTHESIS AND CHARACTERIZATION
Titanium carbide, TiC is a light gray metallic colored carbide type with 20.05% carbon content. Titanium carbide (TiC) which has possess excellent properties such as high melting point, hardness, abrasion and corrosion resistance and excellent electrical and thermal conductivity. For instance, refractories, cutting tools, electronics, chemical resistant materials are all wide range of application areas of titanium carbide (TiC). Smaller carbide particles are high-cost material in order to produce fine-grained composites. The main purpose of this study is to synthesize lower cost nanoparticles by carbothermal and sol-gel method. The sol-gel method provides high homogenity in the chemical composition of the final product since the original components can be mixed at the molecular or atomic level using titanium (IV) butoxide (TBOT), acetylacetone (ACAC) and acetic acid (AcOH). Sucrose is selected as the carbon source. Because, it can be completely decomposed into carbon and H 2 O. Thus, the C/Ti molar ratio in the Ti-O-C precursor can be completely fixed. The sol-gel technique combined with carbothermal reduction is a promising method for producing fine particle size and high purity carbide ceramics at a relatively low temperature.
