Lithium-free heat-resistant ceramic and preparation method thereof
The invention relates to the technical field of heat-resistant ceramics, and particularly discloses a lithium-free heat-resistant ceramic and a preparation method thereof, the lithium-free heat-resistant ceramic comprises the following raw materials: Zhangzhou black soil, Guizhou soil, bauxite, Xinyang soil, porcelain powder, Datong soil, fused quartz, a modifier and a binder; the preparation method comprises the following steps: jointly adding Zhangzhou black soil, Guizhou soil, bauxite, Xinyang soil, porcelain powder, Datong soil and fused quartz into a grinding machine, performing primary grinding and mixing, and adding a modifier for secondary grinding and modification to obtain mixed fine powder; adding a binder into the mixed fine powder, mixing and granulating, performing compression molding to obtain a required green body, and heating and sintering the green body to obtain the required lithium-free heat-resistant ceramic. The raw materials are simple in selection and low in cost, and the various raw materials have a synergistic effect, so that different components can be better fused with one another in the sintering process, the compactness and glossiness of the ceramic are improved while the optimal heat-resistant ceramic is obtained, and the obtained heat-resistant ceramic has relatively high stability and controllability.
本申请涉及耐热陶瓷技术领域，具体公开了一种无锂耐热陶瓷及其制备方法，所述无锂耐热陶瓷包括原料：漳州黑土、贵州土、铝矾土、信阳土、瓷粉、大同土、熔融石英、改性剂、粘结剂；其制备方法为：将漳州黑土、贵州土、铝矾土、信阳土、瓷粉、大同土和熔融石英共同加入到研磨机中，进行一次研磨混合后，加改性剂进行二次研磨改性，得混合细粉；将混合细粉加粘结剂混合造粒后，压制成型得所需坯体，将坯体升温烧结即得所需的无锂耐热陶瓷；本申请原料选用简单，成本低，多种原料协同作用，使得烧结过程中不同成分能够更好地相互融合，保证获得最佳耐热性能陶瓷的同时，增加陶瓷的致密性和光泽度，所得耐热陶瓷具有较高的稳定性和可控性。
