Ceramic material as well as preparation method and application thereof

The invention discloses a ceramic material and a preparation method and application thereof. The transmittance of the ceramic material in a visible light wave band is 5%-65%, the L value of Lab values is 50-100, the a value is-5 to + 5, and the b value is-5 to + 15. The haze is greater than or equal to 50%; the density is 2.3 g/cm < 3 >-2.7 g/cm < 3 >, and the relative dielectric constant is 5-6. The zirconium oxide ceramic can be used as a mobile phone backboard or a backboard of wearable equipment or a notebook computer touch panel or a tablet computer backboard instead of zirconium oxide ceramic. 本发明公开了一种陶瓷材料及其制备方法和应用，该陶瓷材料在可见光波段透过率为5%-65%，Lab值的L值为50-100，a值为-5至+5，b值为-5至+15；雾度≥50%；密度介于2.3g/cm3-2.7g/cm3，相对介电常数为5-6。可以代替氧化锆陶瓷用作手机背板或可穿戴设备的背板或笔记本电脑触控板或平板电脑背板。
