Abstract

PROCEDIMIENTO PARA PREPARAR HIDROXILPATITO EN REACCIONES A TRAVES DE SOLUCION, EN DONDE EL FOSFATO DE CALCIO MONOBASICO SE HACE REACCIONAR CON UNA SOLUCION DE HIDROXIDO DE CALCIO. SE FORMA UNA MEZCLA PREVIA DE CARACTER ACIDO HACIENDO REACCIONAR ACIDO FOSFORICO E HIDROXIDO DE CALCIO CON AGITACION CON ELEVADO CIZALLAMIENTO EN UNA PRIMERA ETAPA, Y HACIENDO REACCIONAR DESPUES LA MEZCLA PREVIA DE CARACTER ACIDO CON UNA SOLUCION SATURADA DE HIDROXIDO DE CALCIO, TAMBIEN CON AGITACION CON ELEVADO CIZALLAMIENTO, EN UNA SEGUNDA ETAPA. LA REACCION DE LA SEGUNDA ETAPA SE LLEVA A CABO EN UNA SOLUCION ALCALINA INTRODUCIENDO CUIDADOSAMENTE LA MEZCLA PREVIA DE ACIDO EN LA SOLUCION DE HIDROXIDO DE CALCIO CON LO QUE EL PH DE LA SOLUCION SE MANTIENE POR ENCIMA DE 11 HASTA QUE LA REACCION ESTA PROXIMA A COMPLETARSE. SE PREFIERE PARTICULARMENTE UTILIZAR UNA PARTE ESTEQUIOMETRICA DE HIDROXIDO DE CALCIO PARA LLEVAR A CABO LAS REACCIONES.
