The invention discloses a multicolor ceramic part and a preparation method thereof. The method for preparing the multicolor ceramic part comprises the following steps: performing dry pressing molding on first-color ceramic powder to obtain a first green body; carrying out first processing treatment on the first green body to form a groove; injecting at least one second color ceramic slurry into the groove, and drying to obtain a second green body; and degreasing and sintering the second green body to obtain the multicolor ceramic piece. Therefore, the first color ceramic powder is subjected to dry pressing molding to obtain the first green body, and the first green body does not need to be presintered independently, so that the preparation cost is reduced; in the ceramic piece prepared by the method, ceramics with different colors are tightly combined, and the ceramic piece also has a better appearance effect.

本发明公开了多色陶瓷件及其制备方法。制备多色陶瓷件的方法包括：将第一颜色陶瓷粉料进行干压成型，得到第一坯体；对所述第一坯体进行第一加工处理，形成凹槽；将至少一种第二颜色陶瓷浆料注入所述凹槽中，干燥后得到第二坯体；对所述第二坯体进行脱脂烧结，得到多色陶瓷件。由此，第一颜色陶瓷粉料通过干压成型得到第一坯体，不需要单独对第一坯体进行预烧结，有利于降低制备成本；利用上述方法制备得到的陶瓷件中不同颜色的陶瓷之间结合紧密，陶瓷件也具有更好的外观效果。
