The invention discloses a corrosive for displaying the sintering ferrite microstructure and application of the corrosive, the corrosive comprises hydrochloric acid, stannous chloride and deionized water, the hydrochloric acid concentration of the corrosive is 15%-18% (mass fraction), and the stannous chloride concentration is 8%-10% (mass fraction); the corrosive is prepared from the hydrochloricacid with the concentration being 30%-37% (mass fraction), the stannous chloride and the deionized water. Display of the sintering ferrite microstructure by the corrosive comprises the following stepsthat sintering ferrite samples are subjected to mechanical grinding and mechanical polishing sequentially, the sintering ferrite samples are soaked into the corrosive under the room temperature condition, and the sintering ferrite microstructure can be clearly displayed under a microscope after corrosion. The sintering ferrite samples can be corroded under the room temperature condition by the corrosive, the microstructur
