Title (EN) METHOD OF PRODUCING SURGICAL GRADE CALCIUM SULPHATE
(FR) METHODE DE PRODUCTION DE SULFATE DE CALCIUM DE QUALITE CHIRURGICALE
Abstract: front page image
(EN)A method of producing surgical grade calcium sulphate suitable for use as resorbable osteoconductive bone void filler material. The method comprising forming an initial calcium sulphate di-hydrate from synthetic constituents; dehydrating the initial calcium sulphate di-hydrate to form calcium sulphate anhydrite; and subsequently rehydrating the calcium sulphate anhydrite and allowing subsequent calcium sulphate di-hydrate to crystallise out.
(FR)L'invention concerne une méthode de production d'un sulfate de calcium de qualité chirurgicale, destiné à être utilisé comme matériau d'apport de cavité osseuse ostéoconductive résorbable. La méthode consiste à : former un di-hydrate de sulfate de calcium initial à partir de constituants synthétiques ; déshydrater le di-hydrate de sulfate de calcium initial pour former une anhydrite de sulfate de calcium ; réhydrater ultérieurement l'anhydrite de sulfate de calcium et permettre à celle-ci de se cristalliser.
