Abstract

See full text

A negative thermal expansion material having a negative thermal expansion coefficient according to the present invention is represented by Zr2−aMaSxP2O12+δ, where M is at least one selected from Ti, Ce, Sn, Mn, Hf, Ir, Pb, Pd, and Cr; a is 0≤a<2; x is 0.4≤x≤1; and δ is a value defined as to satisfy a charge neutral condition. The present invention makes it possible to provide a negative thermal expansion material, a composite material and a method for producing a negative thermal expansion material that can realize reduction in cost and density reduction.
