Inorganic structure and method for producing same

Abstract

Provided is an inorganic structure including a plurality of magnesium oxide particles; and a binding part that covers a surface of each of the magnesium oxide particles and binds the magnesium oxide particles together. The binding part contains an amorphous compound containing silicon, a metallic element other than silicon, and oxygen, and contains substantially no alkali metal, B, V, Te, P, Bi, Pb, and Zn. Also provided is a method for producing an inorganic structure including: a step for obtaining a mixture by mixing a plurality of magnesium oxide particles, a plurality of amorphous silicon dioxide particles, and an aqueous solution containing a metallic element other than silicon; and a step for pressurizing and heating the mixture under conditions of a pressure of 10 to 600 MPa and a temperature of 50 to 300° C.
