The invention discloses a preparation method of composite ceramic with thermal shock resistance. The preparation method comprises the following steps: (1) dividing kaolin into a part a and a part b; (2) calcining the a parts of kaolin to obtain calcined kaolin; (3) carrying out electrolysis treatment on the b parts of kaolin to obtain electrolyzed kaolin; (4) respectively grinding and sieving thecalcined kaolin, the electrolytic kaolin, the potassium feldspar, the aluminum oxide powder, the cordierite and the spodumene, then carrying out vacuum pugging, molding and drying, and then glazing byadopting glaze to obtain a bowl blank; (5) carrying out firing molding on the bowl blank, and performing natural cooling to room temperature to obtain the product. According to the composite ceramicprepared by the method, the mechanical property and the thermal shock resistance are greatly improved, so that the application field of the composite ceramic is greatly expanded.
本发明公开了一种具有抗热震性能的复合陶瓷制备方法；涉及陶瓷技术领域，包括以下步骤：（1）将高岭土分成a、b两份；（2）对a份高岭土进行煅烧处理，得到煅烧高岭土；（3）对b份高岭土进行电解化处理，得到电解高岭土；（4）将煅烧高岭土、电解高岭土、钾长石、氧化铝粉、堇青石、锂辉石分别进行研磨，过筛，然后进行真空练泥、成型、干燥，然后采用釉料施釉而得到碗坯；（5）将碗坯进行烧制成型，自然冷却至室温，即得；本发明方法制备的复合陶瓷通过极大的改善了其力学性能和抗热震性能，从而大幅度的提高了其应用领域。
