Preparation method of high-strength wide-firing-range prestressed magnesian domestic porcelain and product prepared by preparation method of high-strength wide-firing-range prestressed magnesian domestic porcelain
The invention discloses a preparation method of high-strength wide-firing-range prestressed magnesium domestic porcelain and a prepared product, a coating is introduced on the surface of a magnesium domestic porcelain green body through a coating technology, and the thermal expansion coefficient difference of different crystal phases of the coating and the magnesium domestic porcelain green body is utilized, so that the thermal expansion coefficient of the green body surface is reduced to generate pre-compression stress, and the high-strength wide-firing-range prestressed magnesium domestic porcelain is obtained. The effect of enhancing the breaking strength of the green body is achieved, meanwhile, the thermal stability of the ceramic is improved, the requirement of the magnesium domestic ceramic for the strength and the thermal stability is met, and the method has very important significance for innovation and development of the domestic ceramic.
本发明公开了一种高强度宽烧成范围预应力镁质日用瓷的制备方法及其制得的产品，通过涂层技术在镁质日用瓷坯体表面引入涂层，利用两者不同晶相的热膨胀系数差，从而使得坯体表面的热膨胀系数下降产生预压缩应力，实现了增强坯体抗折强度的效果，同时提升了陶瓷的热稳定性，解决了镁质日用瓷对强度和热稳定性的需求问题，对日用陶瓷创新和发展具有十分重要的意义。
