  • Patent number: 11261089
    Abstract: An object of the present invention is to provide anhydrous dibasic calcium phosphate having good powder flowability and good dispersibility in water. An anhydrous dibasic calcium phosphate powder containing agglomerated particles formed by agglomerating anhydrous dibasic calcium phosphate particles having a modal pore diameter/mean particle diameter ratio of 0.2 to 0.34 exhibits good powder flowability and good dispersibility in water.
    Type: Grant
    Filed: March 23, 2018
    Date of Patent: March 1, 2022
