Properties of diopside, CaMgSi2O6, powder prepared from metal alkoxides were investigated examine for its application as a biomaterial. Gel powder was synthesized by hydrolysis of mixed alkoxides, i.e. Ca(OEt)2, Mg(OC2H4OEt)2 and Si(OEt)4. The hydrolyzed product was characterized by SEM, DTA, XRD, ICP and so on. The dry gel powder was X-ray amorphous and crystallized into diopside at 840°C. This amorphous powder showed better sinterability than that of the crystallized powder. The calcined powder could be coated on Ti metal by a thermal treatment at 800°C for 2h. The diopside coated Ti metal composite was expected to be useful for biomaterials as artificial bone and dental root.
