  • Patent number: 9040156
    Abstract: This invention relates to whitlockite and a method for manufacturing the same. The method includes adding, to water, a calcium ion supplying material and a cation supplying material containing a cation (X) other than the calcium ion to prepare a cation aqueous solution, adding a phosphoric acid supplying material to the cation aqueous solution, and aging the cation aqueous solution including the phosphoric acid supplying material. As a result, whitlockite having high purity and high crystallinity can be mass produced using a simple process.
    Type: Grant

  • Patent number: 8951462
    Abstract: Provided is a method of manufacturing porous ceramic bodies with gradient of porosity, in which a gradient that is continuous to a pore size and porosity is precisely controlled in a simple way. The method includes the steps of: obtaining molded bodies by pressurizing and molding a mixture of powder obtained by mixing ceramic powder and polymer powder at a weight ratio of 1:1 to 100:1; and obtaining sintered bodies with gradient of porosity by sintering the molded bodies while applying a gradient pressure to the molded bodies.

  • Publication number: 20140161742
    Abstract: This invention relates to oral composition. The oral composition comprises whitlockite. The oral composition may further comprise fluoride ion. The whitlockite may have a chemical formula represented by Ca20-yXy(HPO4)2(PO4)12, and a ratio of Ca:X:P may be (1.28±0.2):(0.14±0.02):1. The oral composition may have good cleaning effect and tooth decay prevention effect.
