BASE MATERIAL MADE OF TITANIUM METAL AND CELL CULTURE MATERIAL USING THE SAME, IMPLANT MATERIAL AND PHOTOCATALYST FILTER

摘要

PPROBLEM TO BE SOLVED: To provide a base material made of titanium metal having a large surface area per unit volume as well as sufficient strength to function as a base material. PSOLUTION: The base material made of titanium metal has a net-like weathered layer of 0.1 to 20 m in depth, which is formed by immersing a thin piece of titanium metal of 300 m or less in thickness in an aqueous alkaline solution of 5 N or lower for 0.5 to 12 hours. For the thin piece of titanium metal, a titanium fiber whose radius is 300 m or less or titanium sheet whose thickness is 300 m or less is suitable. PCOPYRIGHT: (C)2008,JPO&INPIT
