Production method of polycrystalline transparent ceramics for electronic products
The present invention discloses a production method of polycrystalline transparent ceramics for electronic products. The production method comprises the following steps: 1, polycrystalline transparent ceramic cutting; 2, edge grinding processing; 3, grinding, plasma etching surface for damaged layer removal and destressing, and edge etching with a solution; 4, annealing; 5, polishing; 6, wahsing; and 7, film coating. After the traditional processes of edge grinding and smoothing, the processes of plasma etching surface for damaged layer removal and destressing as well as etching for damaged layer removal and destressing are added, sand mouths of surface damaged stress layers and edges of the polycrystalline transparent ceramics after edge grinding removal and smoothening, finally the strength of the polycrystalline transparent ceramics is greatly improved, thus, polycrystalline transparent ceramic products can meet strength requirements of various electronic products.
