Claim Text:
1. Single-crystal apatite nanowires sheathed in graphitic shells, synthesized by i) introducing into a reactor either a material including an element corresponding to X of X 5 (YO 4 ) 3 (Z), which is a chemical formula for apatite, or a substrate containing the material, ii) maintaining the inside of the reactor in a vacuum and supplying a carrier gas to the reactor, iii) increasing the temperature of the reactor to synthesis temperature, iv) supplying reactant gases comprising carbon and phosphorus sources to the reactor and allowing the reactant gases to react with the material or substrate introduced into the reactor in step i), and v) cooling the reactor to room temperature in a carrier gas atmosphere, wherein the nanowires have a diameter of 5-20 nm and a length of 100 nm to 5 μm, in which the graphitic shells have a thickness of 0.34-2 nm, and the apatite cores comprise 99-100% of the inner cavity of the graphitic shells.
