Preparation method of zirconia ceramic mobile phone backboard with black gold sand effect
The invention discloses a preparation method of a zirconia ceramic mobile phone backboard with a black and golden sand effect. The ceramic is formed by dispersing black and golden sand-like points in a matrix. The preparation method comprises the following steps: adding different particle grades of white zirconia ceramic particles with the alumina content of 10-30% into black zirconia ceramic granulation powder with specific components, mixing, carrying out dry pressing molding to obtain a rear cover green body in 2D, 2.5 D and 3D shapes, and carrying out isostatic pressing, degreasing, sintering, grinding, CNC (computer numerical control) and polishing to obtain the ceramic rear cover. The method is simple in preparation technology, the production process is easy to control, and large-scale mass production is easy to realize; and the appearance is attractive, the surface has a jade-like effect, and the market individuation requirement can be met.
本发明公开了一种黑金沙效果氧化锆陶瓷手机背板的制备方法，该陶瓷由基体黑色、金色沙状点散布于基体中组成，本发明的制备方法为：将具有特定组份的黑色氧化锆陶瓷造粒粉中加入不同颗粒等级的氧化铝含量10%~30%的白色氧化锆陶瓷颗粒，混合后干压成型为2D、2.5D、3D形状的后盖生坯，经等静压、脱脂、烧结、研磨、CNC、抛光后加工成陶瓷后盖。本发明方法制备技术简单，生产过程易于控制，易于实现规模化量产；外观优美，表面玉石般效果，可满足市场个性化需求。
