| 摘要 |
<p>The present invention provides a setter used in firing, which, when fired, forms a crystalline phase comprising the same main component as in the crystalline phase formed when a to-be-fired body is fired together with the setter and which has a surface roughness Ra of 8 to 50 µm at the surface to come in contact with the to-be-firmed material. With the setter used in firing, of the present invention, the fired honeycomb body produced as a product is free from cell defect or lack of cells, and also free from the crack by firing, cell-deformation, cracking, deformation or undesired reaction, all caused by the mismatching of expansion and shrinkage between the setter and the to-be-fired body; therefore, there can be prevented a reduction in yield in production of a fired honeycomb body (a product).</p> |
