Abstract
There is provided a constraining green including a first constraining layer having a surface disposed on the one of the top and bottom surfaces of the ceramic laminated body, the first constraining layer containing a first inorganic powder; and a second constraining layer disposed on a top of the first constraining layer and containing a second inorganic powder and a fly ash. The constraining green sheet serves to ensure less shrinkage of the ceramic laminated body and improve debinding characteristics.
Claims4
A constraining green sheet to be disposed on one of top and bottom surfaces of a non-sintered ceramic laminated body, the constraining green sheet comprising:
- a first constraining layer having a surface disposed on the one of the top and bottom surfaces of the ceramic laminated body, the first constraining layer containing a first inorganic powder;
- and
- a second constraining layer disposed on a top of the first constraining layer and containing a second inorganic powder and a fly ash,
- wherein the fly ash is capable of being burned to ensure a passage for debinding during sintering of the ceramic laminated body, burning temperature of the fly ash being lower than a sintering temperature of the ceramic laminated body.
