NEGATIVE THERMAL EXPANSION MATERIAL, METHOD FOR MANUFACTURING SAME, AND COMPOSITE MATERIAL
An object of the present invention is to provide a negative thermal expansion material having better negative thermal expansion characteristics. The present invention is a negative thermal expansion material, comprising copper vanadium composite oxide powder dissolving Al atoms and represented by the following general formula (1): CuxMyVzOt (1)wherein M represents a metallic element with an atomic number of 11 or more other than Cu, V, and Al, 1.60 ≤ x ≤ 2.40, 0.00 ≤ y ≤ 0.40, 1.70 ≤ z ≤ 2.30, 6.00 ≤ t ≤ 9.00, 1.00 ≤ x + y ≤ 3.00, and a molar number of the Al atoms in terms of atoms > a molar number of M atoms in terms of atoms if an M element is contained.
