Negative thermal expansion material, manufacturing method thereof and composite material
The invention aims to provide a negative thermal expansion material with excellent negative thermal expansion performance. This negative thermal expansion material is characterized by containing a copper-vanadium composite oxide represented by general formula (1) in which Li atoms are solid-solved, and in the formula (1), M represents a metal element having an atomic number of 11 or more other than Cu and V, x represents 1.60 < = x < = 2.40, y represents 0.00 < = y < = 0.40, a represents 1.60 < = a < = 2.40, b represents 0.00 < = b < = 0.40, and t represents 5.00 < = t < = 9.00 (where 1.60 < = x + y < = 2.40 and 1.60 < = a + b < = 2.40).
本发明目的在于提供一种具有优异的负热膨胀性能的负热膨胀材料。本发明的负热膨胀材料其特征在于，包含固溶有Li原子的下述通式(1)所示的铜钒复合氧化物，(CuxMy)(VaPb)Ot(1)式中，M表示Cu和V以外的原子序号11以上的金属元素，x表示1.60≤x≤2.40，y表示0.00≤y≤0.40，a表示1.60≤a≤2.40，b表示0.00≤b≤0.40，t表示5.00≤t≤9.00，其中，1.60≤x+y≤2.40，1.60≤a+b≤2.40。
