Title:
SILICA-(CALCIUM PHOSPHATE) COMPOSITE BLOCK BODY, AND METHOD FOR PRODUCING SILICA-(CALCIUM PHOSPHATE) COMPOSITE BLOCK BODY
Document Type and Number:
WIPO Patent Application WO/2024/029412
Kind Code:
A1
Abstract:
Provided is a silica-(calcium phosphate) composite block body which has high strength and cannot be disintegrated in water and furthermore shows an excellent bone production capability. The silica-(calcium phosphate) composite block body is characterized by being cured as the result of the chemical bonding between inorganic components or the entanglement or fusion of crystals of the inorganic components, in which calcium phosphate containing silisic acid in the crystal structure thereof is contained, the volume of the composite block body is 2.0 mm3 or more, and the DTS strength of the composite block body is 0.1 MPa or more.
