摘要： Method and apparatus for preparing of at least one ceramic shaped part. A cavity is provided between at least one external shape and at least one internal shape. A Si-containing powder composition is then provided in the cavity. The composition is then heated in a reactive gas atmosphere to obtain a reaction bounded ceramic shaped part. Use of the apparatus is also described.
