Colored ceramic body bottom and preparation method thereof
The invention belongs to the technical field of ceramic production, and discloses a colored ceramic body bottom and a preparation method thereof, and the method comprises the following steps: carrying out compression molding on a ceramic base material to obtain a ceramic body; applying a color developing agent on the base of the ceramic body, wherein the color developing agent comprises a cobalt-containing compound; drying the ceramic green body coated with the color developing agent, and calcining until the color of the green body bottom of the ceramic green body is changed; wherein the ceramic green body contains aluminosilicate, Al2O3 is generated when the aluminosilicate is calcined at a high temperature, and when the ceramic green body is continuously calcined at a high temperature, the cobalt-containing compound reacts with Al2O3 in the ceramic green body to generate CoAl2O4, so that the color of a coating surface of the ceramic green body is changed. The low-cost cobalt-containing compound is used as the color development material of the ceramic green body, so that the production cost is reduced while the color development grade of the product is not influenced, and the technical problem of color development difference of the ceramic green body product using the traditional low-price raw material green body is solved.
本发明属于陶瓷生产技术领域,公开了一种彩色陶瓷坯底及其制备方法，其中所述方法包括以下步骤：将陶瓷基料压制成型以获得陶瓷坯体；在陶瓷坯体的坯底上施显色剂，所述显色剂包括含钴化合物；将涂抹有所述显色剂的陶瓷坯体进行干燥，并进行煅烧直至陶瓷坯体的坯底的颜色发生改变；其中，陶瓷坯体中包含有铝硅酸盐，铝硅酸盐在高温煅烧时生成Al2O3，继续对陶瓷坯体高温煅烧时，所述含钴化合物与陶瓷坯体中的Al2O3发生反应生成CoAl2O4，以改变陶瓷坯体涂附面的颜色。本发明通过低成本的含钴化合物作为陶瓷坯体的发色材料，在不影响产品显色档次的同时降低了生产成本，解决了陶瓷坯体产品使用传统低价原料坯体发色差的技术问题。
