Abstract: The present invention pertains to injectable heat generating biocompatible ceramic compositions based on hydraulic calcium aluminate, which can be used for therapeutic treatment in vivo, such as tumour treatment, pain control, vascular treatment, drug activation etc, when curing in situ, and which form a biocompatible solid material that can be left in the body for prolonged periods of time without causing negative health effects. The present invention can also be used to restore the mechanical properties of the skeleton after cancerous diseases.

Abstract: Surface coating method for deposition of a chemically bonded ceramic coating on a substrate, includes the steps of preparing a curable coating slurry, depositing a coating of the slurry on at least a section of the substrate surface, and hardening the slurry. The step of preparing a curable coating slurry includes mixing calcium aluminate powder with water and at least one water-reducing-agent, such that a water-to-cement ratio in the range of 0.1 to 0.9 is achieved.

Abstract: The invention describes a low temperature method for producing multi-layered or multi-phased coatings. With the technique according to the present invention, surface coatings with controlled variations in terms of chemical composition, phase composition, porosity, surface roughness, mechanical properties, biocompatibility, etc can be achieved. The method of coating a substrate surface comprising the steps of preparing one powder mixture, or several powder mixtures having different chemical composition, wherein at least one of said powder mixtures comprise a non-hydrated hydraulic ceramic powder binder phase, pre-treating a substrate surface, to increase the adhesion between the substrate and the ceramic coating, applying one or more different layers on top of each other of the non-hydrated powder mixture on the substrate, and finally, hydrating the powder layer/layers in a curing agent containing ions of carbonates, phosphates or fluorides.

Abstract: A chemically bonded ceramic material based on calcium aluminate hydrate with additives of primarily calcium titanate, but also chemically similar compounds. The material is a biocompatible material for implants, particularly for orthopaedic and dental applications. The material possesses the properties required for an orthopaedic biocement. It cures through reaction with water and develops its strength within a short period of time, has good workability prior to curing, is shape stable, has a low heat generation during curing, and is friendly to adjacent tissues.
