Abstract

In all stages of ceramic processing, synthesis, conditioning, calcination, shaping, drying and sintering, there is the possibility of insertion of inhomogeneities in the material which can evolve to microstructural defects and heterogeneities in the final product, which can hinder their application, and so, all steps should be carefully controlled. In this direction, the rheology is a fundamental tool in setting processing conditions from slurries, related to the drying, transport, forming, surface coatings (enamels), etc., reducing the heterogeneity inherent in ceramic processing. In the case of biomaterials, such as tricalcium phosphate (TCP), one of the most suitable ceramic materials to dental and medical applications, the use of shaping techniques involving concentrated ceramic suspensions for the production of bone grafting elements, supported by rheological knowledge ie adequate, because if well managed, help in obtaining parts with complex geometries homogeneous reproductive way. These products, depending on each specific case, should have different absorption rates in the body that will be dependent on the surface conditions of employees grafting elements. In this work, the objective is to further study the rheological behavior of concentrated suspensions of tricalcium phosphate (TCP) with various solids concentrations and additives, so they can be shaped by bonding in porous molds and impregnation replicas of the form tailor products conformed to surface conditions to meet the demand of bone bioabsorption. The rheological study of tricalcium phosphate suspensions with different solids concentrations and additives in order to meet all the necessary parameters to the above forming processes mentioned will be performed in the laboratories of the Federal University of ABC.
