Glass structure and method for producing the same

Abstract

A glass structure includes: a plurality of glass particles, each of the glass particles including SiO2, CaO and P2O5; and a bonding portion that bonds the glass particles to one another and contains hydroxyapatite, wherein at least a part of the hydroxyapatite is crystalline in the bonding portion, and wherein a porosity of the glass structure is 15% or less. A method for producing the glass structure includes: preparing a mixture by mixing a plurality of glass particles and an aqueous solution with each other, each of the glass particles including SiO2, CaO and P2O5, and the aqueous solution including calcium and phosphorus and having pH of 4.0 or more; and heating and pressurizing the mixture.
