  • Negative thermal expansion material, composite material, and method for producing negative thermal expansion material
    Patent number: 11970396
    Abstract: A negative thermal expansion material having a negative thermal expansion coefficient according to the present invention is represented by Zr2?aMaSxP2O12+?, 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 ? 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.
