In the present perspective, evolution of ferroelectric transition and dielectric properties in tungsten bronze oxides is surveyed, and the physical image of modulation structure is established to interpret the variation of ferroelectric transition and macro ferroelectric properties. Different A site cations lead to different modulation structure, and the relationship between temperatures of modulation structure change and ferroelectric transition dominates the crossover from normal to relaxor ferroelectric in tungsten bronze oxides. At low temperature, modulation structure will lock into a regular space group, while the interactions between modulation structure and ferroelectric order results in the low temperature dielectric relaxations.
