Method for densifying nano-microporous permeable ceramic material
The invention relates to the technical field of ceramic materials, and discloses a nano-microporous permeable ceramic material densification method which comprises the following steps: preparing silica sol by an ion exchange method; selecting a plurality of parts of silica sol with different particle sizes, wherein the content of SiO2 in the silica sol is increased along with the increase of the particle sizes; the silica sol is used for carrying out orthogonal dipping compounding on the quartz ceramic flat plate, and the content of SiO2 in the silica sol adopted in each dipping compounding is not changed or is reduced compared with the content of SiO2 in the silica sol adopted in the previous dipping compounding. According to the method for densifying the nano-microporous permeable ceramic material, the micro-nano silica sol is adopted for orthogonal impregnation compounding, so that the mass density of a quartz ceramic product can be continuously improved, and the internal densification degree of the product is further improved.
本发明涉及陶瓷材料技术领域，公开了一种纳米微孔渗透陶瓷材料致密化方法，包括如下步骤：离子交换法制备硅溶胶；选取若干份不同粒径的硅溶胶，且硅溶胶的SiO2的含量随着粒径的增大而增大；使用硅溶胶对石英陶瓷平板进行正交浸渍复合，每轮浸渍复合采用的硅溶胶中SiO2的含量相比上轮浸渍复合不变或减少。本发明纳米微孔渗透陶瓷材料致密化的方法，采用微纳米级硅溶胶进行正交浸渍复合，可以持续提高石英陶瓷产品的质量密度，进而提升产品内部致密化程度。
