<P>PROBLEM TO BE SOLVED: To provide a silica film containing silicon hydroxide, a bioactive material having the silica film and its formation method. <P>SOLUTION: The silica film is originated from polysilazane containing silicon hydroxide (SiOH), and the bioactive material comprises a base material and the silica film originated from the polysilazane containing the silicon hydroxide. Further, the silica film formation method comprises at least an applying process of applying coating liquid containing the polysilazane to the base material, a burn process of burning the base material to which the coating liquid is applied, and a hydroxy group imparting process executed during or after the burning process. <P>COPYRIGHT: (C)2008,JPO&INPIT |
