FORMATION OF CALCIUM PHOSPHATE FILM |
摘要 |
PURPOSE:To form a calcium phosphate film on a substrate industrially by immersing the substrate in a soln. for deposition prepd. by adding an aqueous hydrogen peroxide soln. to a mixed aqueous soln. contg. a water soluble Ca salt., Ca complexing agent, and water soluble phosphate. CONSTITUTION:A water soluble Ca salt such as calcium nitrate, a complexing agent such as ethylenediaminetetraacetate and a water soluble phosphate such as ammonium dihydrogenphosphate are dissolved in water in 1:(1-1.2): (0.5-0.7)mol ratio, 1-20wt% aqueous hydrogen peroxide soln. is added and the pH of the resulting soln. is adjusted to 6-10. A substrate is immersed in the soln. for depositing calcium phosphate and the soln. is kept at 50-100 deg.C to deposit calcium phosphate on the surface of the substrate. The substrate is then heat treated as required so as to firmly stick a formed calcium phos phate film to the substrate. |
