SILICIC ACID-CONTAINING APATITE

摘要

PROBLEM TO BE SOLVED: To provide a silicic acid-containing apatite excellent in ion exchange performance and antibacterial property. SOLUTION: In manufacturing silicic acid-containing apatite, phosphoric acid ions of hydroxyl apatite are partially replaced with silicate ions. A specific surface area of the silicic acid-containing apatite is in the range of 40-300 m2/g.
