摘要：
Provided is a novel niobate compound that has excellent reactivity with alkali metal salts and can be reacted with alkali metal salts at room temperature.
The niobate compound has a ratio (first peak/second peak) of the intensity of a peak (first peak) having the highest intensity at 2θ = 9.4° ± 1.5° to the intensity of a peak (second peak) having the highest intensity at 2θ = 29.0° ± 1.5° being 1.3 or more in the X-ray diffraction pattern.
