Ceramic structural member and preparation method and application thereof

ZHENG ZHENHONG / QIU JIHUA

The invention discloses a ceramic structural part as well as a preparation method and application thereof. The ceramic structural part comprises a zirconia ceramic substrate and a color matching layer arranged on the inner surface of the zirconia ceramic substrate, the crystal phase of zirconium oxide in the zirconium oxide ceramic substrate is a tetragonal phase; and the preparation raw materials of the color mixing layer comprise 5-30% by mass of pigment. According to the ceramic structural part, by adjusting the adding amount of the pigment in the color matching layer, the color matching layer can present colors of different degrees, the color combination of the zirconia ceramic substrate and the color matching layer achieves controllable adjustment of the appearance chromaticity of the final ceramic structural part, in addition, the reliability of the color matching layer of the ceramic structural part is high, and the service life of the ceramic structural part is prolonged. And the zirconia ceramic substrate is high in light transmittance, and the ceramic is high in density, small in crystal grain and high in strength.
