PhysicoMechanical and Physico-Chemical Properties of Bio-Inert Composite Ceramics

Abstract

Bio-inert ceramics are non-toxic, non-allergenic and non-carcinogenic materials which explain why these are frequently used as orthopedic and dental implants. Unfortunately, these are chemically inert and do not naturally form a direct link with the bone. The research carried studies micro/nanostructure properties and the porosity of the TiO₂-Nb₂O₅ ceramics, used as biocompatible polymer matrix, prepared by different technological regimes. The morphology of the composite samples of TiO₂-Nb₂O₅ was studied using scanning microscopy. The phase identification of the composites was carried by metallographic microscopy. Results obtained show the chemical composition, the technological parameters and the porosity determined, favors formation of sufficiently strong bond between the studied materials and vitreous carbon layers.
