ABSTRACT:
A method for coating substrates with calcium phosphate. The aim of the method is to be able to carry out a simple coating for all materials as well as for particles. To this end, the substrate to be coated is placed in a calcium phosphate gel, whereupon this substrate that is coated with the gel is dried. Afterwards, the calcium phosphate particles not adhering to the substrate are removed. The substrate can also be placed inside a colloidal solution of SiO2containing a calcium phosphate, whereupon the mixture is constantly set in motion, the solvent is removed, and the substrate is provided with a calcium phosphate layer by condensing the colloidal SiO2on the surface of the substrate. The coated substrates can, particularly when it concerns coated particles, be used as a bone substitute material.
