RESTREPO PARRA, ELISABETH; ARANGO ARANGO, PEDRO JOSE  e  CASANOVA TRUJILLO, SIMEÓN. SOME CONCEPTS ABOUT TITANIUM NITRIDE AND TITANIUM CARBIDE. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.157, pp.213-224. ISSN 0012-7353.

In this work a sumary of structural and chemical characteristics of materials commonly employed in industrial applications such as TiN and TiC was realized. The analysis was realized from the phase diagrams of TiN and TiC. This materials present, important characteristics such as melting point, boiling point, polymorphism and solubility among others, are observed. These phase diagrams carry to a best understanding to the material properties. On the other hand, an analysis of chemical bonds that result in the TiN and TiC molecules formation, having into a count that they present ionic, covalent and metallic molecular combination bonds was carried out. Moreover, the hybridization that is produced in order to get stable compounds was considered.

Palavras-chave : Phases; temperature; molecular bonds; hybridization.
