Porcelain plate and production process thereof
The invention discloses a porcelain plate and a production process thereof, and belongs to the technical field of porcelain plate preparation processes. The porcelain plate is prepared through the steps of slurry preparation, tape casting, lamination isostatic pressing, degreasing and sintering, the sintering aid is added in the step of slurry preparation, and the sintering aid can form a liquid phase in the sintering process, so that the generation of closed pores can be reduced, and the porcelain plate with fewer surface gray spot defects is obtained; organic matters in the porcelain plate biscuit are removed by controlling the degreasing condition, and the problem that grey spots appear on the porcelain plate due to closed pores generated by organic matter residues is solved.
本发明公开了一种瓷板及其生产工艺，属于瓷板制备工艺技术领域。本发明通过制备浆料、流延、叠层等静压、脱脂、烧结步骤制备得到瓷板，在制备浆料步骤中添加了助烧剂，助烧剂在烧结过程中可以形成液相，由此可以减少闭气孔的产生，得到表面灰点缺陷较少的瓷板，此外，还通过控制脱脂条件排除瓷板素坯中的有机物，缓解因有机物残留产生闭气孔而导致瓷板出现灰点的问题。
