Transparent ceramic microreactor integrally formed based on 3D printing and preparation method of transparent ceramic microreactor

The invention provides a transparent ceramic microreactor integrally formed based on 3D printing and a preparation method of the transparent ceramic microreactor. The preparation method comprises the following steps: uniformly dispersing ceramic powder in photosensitive resin to form ceramic slurry; wherein the proportion of the ceramic powder is 50-70 wt%; carrying out photocuring 3D printing on the ceramic slurry based on the structure of the transparent ceramic microreactor, so as to obtain a photocuring ceramic green body; and carrying out stepped heating degumming on the light-cured ceramic green body, removing the photosensitive resin, and carrying out vacuum sintering to obtain the transparent ceramic microreactor. The preparation of the high-precision and complex-configuration transparent ceramic microreactor can be realized, and the prepared transparent ceramic microreactor has the characteristics of high temperature and high pressure resistance, acid and alkali corrosion resistance, long service lif
