In-situ generated mullite whisker reinforced ceramic green body and preparation method thereof
The invention discloses an in-situ generated mullite whisker reinforced ceramic green body. The ceramic green body comprises the following raw materials: 70-80 wt% of a basic blank, 1-5 wt% of spodumene, 3-8 wt% of bauxite and 10-20 wt% of andalusite, the basic blank is prepared from the following raw materials: 21 to 24 weight percent of chinastone, 18 to 22 weight percent of potassium feldspar, 30 to 34 weight percent of kaolin, 6 to 11 weight percent of black mud, 4 to 7 weight percent of washing mud, 10 to 14 weight percent of white mud and 1 to 3 weight percent of talc. In addition, the invention also discloses a preparation method of the in-situ generated mullite whisker reinforced ceramic body. By optimizing a formula system, formation of a large number of mullite crystals can be promoted, so that the breaking strength of the ceramic green body is effectively improved, the thickness of a product is reduced, and thin-wall light weight of the building sanitary ceramic green body is realized.
本发明公开了一种原位生成莫来石晶须增强陶瓷坯体，其原料组成为：基础坯料70～80wt％、锂辉石1～5wt％、铝矾土3～8wt％、红柱石10～20wt％；所述基础坯料的原料组成为瓷石21～24wt％、钾长石18～22wt％、高岭土30～34wt％、黑泥6～11wt％、水洗泥4～7wt％、白泥10～14wt％、滑石1～3wt％。此外，还公开了上述原位生成莫来石晶须增强陶瓷坯体的制备方法。本发明通过优化配方体系，能够促进大量莫来石晶体的形成，从而有效提高了陶瓷坯体的抗折强度，有利于减小产品厚度，实现建筑卫生陶瓷坯体薄壁轻量化。
