The invention relates to methods of forming shaped articles from suspensions which include ceramic or metallic powder, or from solutions or suspensions which include one or more pharmaceutical substances or other components. The method comprises the steps of: (a) combining solvent, polymer, cross-linking agent precursor and optional further components and placing into a mould of desired shape; (b) increasing temperature of mould contents to activate cross- linking agent; (c) allowing mould contents to solidify to sufficient extent to remove mould; (d) removing shaped article from the mould.
Cette invention se rapporte à des procédés servant à former des articles moulés à partir de suspensions qui contiennent des poudres céramiques ou métalliques, ou à partir de solutions ou suspensions qui contiennent une ou plusieurs substances pharmaceutiques ou d'autres constituants. Ce procédé consiste: (a) à combiner un solvant, un polymère, un précurseur d'agent de réticulation et d'autres constituants optionnels et à les placer dans un moule ayant la forme souhaitée; (b) à augmenter la température du contenu du moule, en vue d'activer l'agent de réticulation; (c) à laisser le contenu du moule se solidifier jusqu'à un degré suffisant pour permettre le démoulage; et (d) à démouler l'article ainsi moulé.
