Lithium-free thermal shock resistant ceramic material and preparation method thereof
The invention belongs to the technical field of ceramic preparation, and particularly relates to a lithium-free thermal shock resistant ceramic material and a preparation method thereof.The preparation method comprises the following steps that titanium dioxide, aluminum oxide powder, quartz powder, filler and deionized water are mixed to be uniform, and first ceramic slurry is obtained; drying the first ceramic slurry to obtain ceramic prefabricated powder; pressing the ceramic prefabricated powder into blocks, and presintering to obtain a prefabricated body; grinding and mixing the preform, a binder and deionized water to obtain second ceramic slurry; carrying out spray granulation on the second ceramic slurry, and pressing to obtain a ceramic green body; and sintering the ceramic green body to obtain the lithium-free thermal shock resistant ceramic material.
本发明属于陶瓷制备技术领域，具体地说涉及一种无锂质抗热震陶瓷材料及其制备方法，制备方法包括以下步骤：将钛白粉、氧化铝粉、石英粉、填料与去离子水混合均匀，得到第一陶瓷料浆；将所述第一陶瓷料浆烘干，得到陶瓷预制粉；将所述陶瓷预制粉压制成块后进行预烧结，得到预制体；将预制体、粘结剂与去离子水研磨混合，得到第二陶瓷料浆；对第二陶瓷料浆进行喷雾造粒、压制后，得到陶瓷坯体；对所述陶瓷坯体进行烧结处理，得到无锂质抗热震陶瓷材料。
