    • A light-weight yet sturdy ceramic article, is manufactured by initially forming at least one fugitive core (14) including a main portion (15) and at least one holding portion (16) projecting from the main portion and then positioning the fugitive core (14) in a mold cavity bounded by a multitude of bounding surfaces (11, 12) so that the holding portion (16) holds the main portion (15) at predetermined spacings from all of the bounding surfaces (11, 12). This is followed by filling the mold cavity around the fugitive core (14) with a dense slip constituted by ceramic or metal particles in mixture with a liquid medium to form a ceramic or metal preform (19) embedding the fugitive core (14) in its interior and freezing the ceramic or metal preform, then the fugitive core (14) is dissolved and escapes from the interior of the frozen ceramic or metal preform and finally the ceramic preform is converted into the ceramic article.
    • 通过初始形成至少一个包括主要部分(15)的至少一个短暂的芯体(14)和从主要部分突出的至少一个保持部分(16),然后将短暂的芯子( 14)在由多个边界表面(11,12)限定的模具腔中,使得保持部分(16)将主要部分(15)保持在与所有边界表面(11,12)预定间隔。 随后,以与液体介质混合的陶瓷或金属颗粒构成的致密滑动物填充短纤芯(14)周围的模腔,以形成将其中的短暂核心(14)嵌入其中的陶瓷或金属预制件(19) 内部并冷冻陶瓷或金属预成型件,然后将短纤芯(14)溶解并从冷冻陶瓷或金属预制件的内部逸出,最后将陶瓷预制件转化成陶瓷制品。
