The invention provides a mobile phone ceramic rear cover, which comprises a zirconia ceramic body and a 3D glaze layer compounded on the surface of the zirconia ceramic, and the 3D glaze layer comprises granular glaze particles. The zirconia ceramic rear cover with a 3D (three-dimensional) effect is obtained by adopting the glaze with specific composition. According to the zirconia ceramic rear cover, the glaze layer with the 3D effect is compounded on the zirconia ceramic rear cover, the glaze layer shrinks into particles such as spheres and the like on the surface of the base material, the concave-convex stereoscopic impression can be formed on the zirconia ceramic green body, the good light refraction is achieved to generate the bright flash effect, and the good flatness is achieved; and by increasing the content of the high-expansion oxide in the formula, the thermal expansion coefficient of the base material is close to that of the glaze, so that the problem of product deformation is solved.
本发明提供了一种手机陶瓷后盖，包括氧化锆陶瓷本体和复合在氧化锆陶瓷表面的3D立体状釉层；所述3D立体状釉层包括颗粒状的釉粒。本发明采用特定组成的釉料，得到了具有3D立体效果的氧化锆陶瓷后盖。该氧化锆陶瓷后盖上复合有3D立体效果的釉层，釉层在基材表面收缩成球形等颗粒状，不仅能够在氧化锆陶瓷坯体上形成凹凸有致的立体感，具有良好的光线折射而产生亮闪效果，同时还具有良好的平整度，而且还能呈现出多种颜色的效果。本发明还通过提高配方中高膨胀氧化物含量，使基材的热膨胀系数与釉料的热膨胀系数接近，从而解决了产品变形的问题。
