Formación de hidroxiapatita, Ca5(P04)3 OH, en presencia de silicatos Formation d´hydroxyapatite, Ca5(PO4)3 OH, en milieu silicate

Abstract

[ES] La hidroxiapatita, Ca^(POJpH -(HAp), es una fase cristalina que tiene diversas aplicaciones en el ámbito de determinados cementos especiales. Esa fase juega un importante papel en las reacciones de cementos utilizados en medicina para la reconstrucción defunciones del esqueleto. Se utiliza también para mejorar propiedades de materiales de aplicación odontológica. Por otra parte, se está estudiando para desarrollar conglomerantes cerámicos. En el presente trabajo se estudia la compatibilidad en estado sólido de la HAp conJS-CJSy C^S utilizando, a presión atmosférica y recinto abierto, composiciones enlazona rica en cal del sistema CaO - SiO^ - Pp^ Lip dentro de los limites siguientes. CaO: 67-71 % ; SiO^: 318% ; PPy 9-29% (en peso). El tratamiento térmico se realizó en estado sólido y en atmósfera abierta. La identificación de las fases se realizó a través de Difracción de Rayos X, Espectroscopia de Absorción Infrarroja y Análisis Térmico Diferencial.Se dejlne una pequeña zona del diagrama de composición: CaO 69,5-70%: PPr 16,2-19,5%; SiO- 11,1-13,6%. En este campo las fases cristalinas compatibles en estado sólido, formadas a l.OOO^C, son HAp,J^-CJSy CJPS

[EN] Hydroxyapatite Ca^(POJpH (líAp) is a crystalline phase which has several applications within the domain of special cements. This phase takes an important role in the cement reactions for the reconstruction of skeletal functions (medical domain). It is used also to improve properties of dental material. On the other hand, it is investigated to develop chemically bonded ceramics. in this paper we study the formation of HAp with ¡3 - C^ and CJ^S, using some compositions in the rich lime portion of the system CaO-SiO^-Pfi^-Hfi (at atmospheric pressure and open system). These compositions lie in the range of: CaO-67- 71%; SiO^-3-18%; Pp-9-29% (Wt%). The preparations are made using solid state rections, with thermal treatment at open system. The identification of phases was carried out using X-ray diffraction, Infra-Red absorption and Dijferentiel Thermal Analysis.We delimit a spectroscopy little domain lies in the range of CaO-69,5-70%; Pfl-16,2-19,5%; SiO^-11,1-13,6%. Within this domain, the crystalline phases solid state compatibility at temperature near lOOO^C are HAp,J3 - CJS, C,.PS.
