The invention discloses a method for continuously regulating the light absorption properties of zinc oxide ceramics, zinc oxide ceramics and a preparation method. Sintering, programmed cooling, and adjusting the light absorption properties of zinc oxide ceramics by adjusting the sintering temperature and sintering pressure. Using the high temperature, oxygen-deficient and reducing environment of plasma sintering technology, and the pulse current of plasma sintering, it is possible to effectively introduce a large number of oxygen defects and interstitial zinc in zinc oxide ceramics by controlling the sintering temperature. By adjusting the sintering temperature and pressure, the color of zinc oxide ceramics changes from the original white color of zinc oxide to lightened-yellow-dark-yellow-reddish brown. |
