Composite Ceramics Reinforced with Zirconia Nanopowders
Dental porcelain fused to metals (PFM) is one of the most widely applied restoration material, because of its excellent esthetics, biocompatibility and wear resistance [1, 2]. In the literature of specialty (dentistry) there is not made a clear distinction between porcelain and ceramic, while referring to ceramics as being all these materials derived from mixtures of metallic oxides, being in opposition with metal alloys [3-5]. The aim of this study was to obtain and characterize dental porcelains, dentine type, in the following oxide system: SiO2-K2O-Al2O3-Na2O-B2O3-MgOCaO, reinforced with nanometric particles of monoclinic zirconia. The method selected for the preparation of the porcelain powders is through solid-state reactions.
