Production method of the calcium phosphate oversaturation solution and the calcium phosphate crystal thin film production method of utilizing its solution

摘要

(57) Abstract This invention regards the method of producing the thin film of calcium phosphate crystal on the solid surface making use of the production method and its solution of the oversaturation solution of the calcium ion and the phosphate ion. Especially, you can control the precipitation of the calcium phosphate in the aqueous solution by low making, adding temperature, selectively the appropriate buff system you use, because of this, can produce the oversaturation solution of the calcium ion and the phosphate ion of high density. And making use of that solution, on the solid surface reactivity to be high can produce the calcium phosphate crystal thin film where the quality whose crystallinity is low is excellent at brief. In addition, the calcium phosphate crystal thin film which is produced by this invention has organism compatibility, can utilize as the living thing material.
