Sintered bodies containing zirconia-based ceramic materials and partially sintered bodies that are intermediates in the preparation of the sintered bodies are described. The zirconia-based ceramic material is doped with lanthanum and yttrium. The grain size of the zirconia-based ceramic material can be controlled by the addition of lanthanum. The crystalline phase of the zirconia-based ceramic material can be influenced by the addition of yttrium. 本发明涉及掺杂钇和镧的基于氧化锆的材料。具体地，本文描述了包含基于氧化锆的陶瓷材料的烧结体和作为烧结体的制备过程中的中间体的部分烧结体。所述基于氧化锆的陶瓷材料掺杂有镧和钇。所述基于氧化锆的陶瓷材料的晶粒度可通过添加镧进行控制。所述基于氧化锆的陶瓷材料的结晶相可通过添加钇来影响。
