High-performance magnesian reinforced porcelain blank, high-performance magnesian reinforced porcelain product and preparation method thereof
The invention discloses a high-performance magnesian reinforced porcelain blank, a high-performance magnesian reinforced porcelain product and a preparation method thereof, and belongs to the technical field of domestic ceramics. The high-performance magnesian reinforced porcelain blank comprises a base material and an additive, wherein the base material comprises the following components in percentage by mass: 25-40 wt% of black magnesia clay, 6-12 wt% of Guangxi resource clay, 8-15 wt% of Guizhou clay, 30-45 wt% of calcined talc, 1-3 wt% of aluminophosphate, 1-5 wt% of caustic calcined magnesia, 3-8 wt% of potassium feldspar, 1-3 wt% of calcite and 1-3 wt% of bentonite; the additive is zirconium oxide micro-powder, and the dosage of the additive is 1-3wt% of that of the base material. Byimproving a formula system, particle dispersion toughening and strengthening are realized, and low-expansion crystals or solid solution is formed in situ, so that the thermal shock resistance of themagnesia porcelain is effectively improved.
本发明公开了一种高性能镁质强化瓷坯料、高性能镁质强化瓷制品及其制备方法，属于日用陶瓷技术领域。所述高性能镁质强化瓷坯料包括基料和添加剂，所述基料包括按照质量百分比计的如下组分：黑色镁质粘土25～40wt%、广西资源粘土6～12wt%、贵州粘土8～15wt%、烧滑石30～45wt%、磷铝石1～3wt%、轻烧镁1～5wt%、钾长石3～8wt%、方解石1～3wt%、膨润土1～3wt%；所述添加剂为氧化锆微粉，其用量为基料的1～3%wt。本发明通过改进配方体系，实现颗粒弥散增韧增强，并原位形成低膨胀晶体或固熔体，从而有效提升镁质瓷的抗热震性能。
