Abstract
A dense coating of a calcium phosphate compound is formed on the surface of a bioadaptable ceramic substrate by applying to the ceramic calcium metaphosphate alone or a mixture of calcium metaphosphate with calcium pyrophosphate, heat-treating the applied layer thereby fusing the applied layer to the surface of the ceramic, then applying to the fused layer a slurry resulting from the mixture of calcium metaphosphate with tetracalcium phosphate, and subsequently heat-treating the applied layer of the slurry thereby inducing reaction of the slurry.
