摘要：
The invention relates to a method for producing a ceramic, a ceramic produced according to said method and to the use thereof. According to the invention, a green body, which consists of at least two different powder mixtures that are compacted to form a moulded body, is initially produced and subsequently sintered. Said powder mixtures respectively contain a ceramic powder and a coloured metal compound and/or a coloured pigment. The two powder mixtures are different in their composition from the coloured metal compound and/or the coloured pigment. The ceramics are shaped prior to sintering and/or during the intermediate step, during which sintering is interrupted and then continued after shaping. The inventive ceramic can be used as colour gradiated dental ceramics or as dental ceramics having a coloured gradient.
摘要（中）：
本发明涉及一种用于制造陶瓷，通过该方法和它们的用途制备的陶瓷。 在本处理中，首先，它由一个生坯在至少两个不同的，压缩以形成一个模制粉末混合物，每个含有陶瓷粉末和着色金属化合物和/或着色颜料，其特征在于，在其着色金属化合物的组合物，每一种情况下两种粉末混合物和/ 不同或彩色颜料制备并随后被烧结，其特征在于，所述陶瓷在烧结之前的成形和/或作为在其期间烧结被中断并继续成形发生之后的一个中间步骤。 根据本发明制备的陶瓷是合适的颜色分级的牙科陶瓷或具有颜色梯度的牙科陶瓷。
