Abstract

The disclosure relates to a zirconia ceramic, a zirconia ceramic shell and a preparation method thereof. A method for preparing zirconia ceramics, comprising: providing a zirconia ceramic substrate; preparing and forming an optical coating layer on the first surface of the zirconia ceramic substrate to improve the transmission of the zirconia ceramic substrate in the visible light range rate to obtain zirconia ceramics. The present disclosure prepares an optical coating layer on the surface of zirconia ceramics, and uses the optical properties of the optical coating layer to change the reflection and transmission characteristics of the surface of zirconia ceramics, which can weaken or eliminate the grey-yellow phase of zirconia ceramics itself, and beautify the appearance of zirconia ceramics As a result, it can also improve the transmittance of zirconia ceramics in the visible light range, and improve the appearance and texture of zirconia ceramics.

Description

technical field [0001] The disclosure relates to the technical field of shell processing, in particular to a zirconia ceramic, a zirconia ceramic shell and a preparation method thereof. Background technique [0002] Zirconia ceramics are a new type of ceramic material with many excellent properties such as wear resistance, corrosion resistance, high strength, high toughness, and good thermal stability. Compared with metals and plastics, zirconia ceramics have the characteristics of high Mohs hardness, high dielectric constant, no signal shielding and good biocompatibility, and have broad application prospects in smartphones and wearable devices, which makes zirconia Zirconium ceramics start from fingerprint identification cover and mobile phone back cover, and will gradually cut into the mobile terminal industry chain, becoming the third largest mobile phone back panel material after plastic and metal. [0003] Zirconia powder itself is a white powder, and the ceramics prep...
