MUMBAI, India, Aug. 1 -- Intellectual Property India has published a patent application (202517044413 A) filed by Nagoya Institute Of Technology; and Orthorebirth Co. Ltd., Aichi, Japan, on May 7, for 'method for modifying crystalline calcium phosphate particles into amorphous calcium phosphate by wet grinding.'
Inventor(s) include Kasuga Toshihiro.
The application for the patent was published on Aug. 1, under issue no. 31/2025.
According to the abstract released by the Intellectual Property India: "Provided is a method for modifying crystalline calcium phosphate particles into amorphous calcium phosphate by wet grinding using a bead mill, without causing particle agglomeration. A slurry that contains calcium phosphate particles and beads in acetone is prepared by introducing crystalline calcium phosphate particle powder and beads in quantities to make an apparent volume ratio of 1:2 to 4 into the vessel of a bead mill, introducing acetone into the mixture of calcium phosphate particle powder and beads in the vessel in a quantity to make the weight ratio of the two 1:5 to 10, and stirring. With the slurry housed in the vessel, the crystalline calcium phosphate particle powder contained in the slurry is finely ground without being caused to agglomerate, and the crystalline calcium phosphate particles are made partially amorphous."
The patent application was internationally filed on Oct. 30, 2023, under International application No.PCT/JP2023/039070.
