Preparation method of sesquioxide ceramic
The invention discloses a sesquioxide ceramic preparation method, which comprises the following steps: adopting an ABA laminated structure during biscuit forming, respectively covering the upper layer and the lower layer of sesquioxide powder B with a layer of mixed powder A which is prepared by ball-milling sesquioxide and magnesium oxide according to a certain proportion, and carrying out compression forming in an ABA type structure, and in the sintering process, grinding the layer A on the upper and lower surfaces of the sesquioxide B, and polishing to obtain the sesquioxide ceramic. According to the invention, residual micropores can be eliminated as much as possible, and scattering loss caused by the micropores is reduced.
本发明公开了一种倍半氧化物陶瓷制备方法，在素坯成型时采用ABA叠层结构，在倍半氧化物粉体B的上层和下层分别覆盖一层由倍半氧化物与氧化镁以一定比例球磨制成的混合粉体A，以ABA型结构压制成型，在烧结过程中将成为倍半氧化物B的上下表面的A层研磨后，抛光得到倍半氧化物陶瓷。本发明可以最大可能排除残余微气孔，降低微气孔的存在造成的散射损耗。
