CORDIERITE COMPOSITIONS FOR IMPROVED EXTRUSION PROCESS QUALITY
PROBLEM TO BE SOLVED: To reduce fast flow webs.SOLUTION: A method of making the green ceramic body comprises the steps of: providing a green ceramic batch material comprising cordierite precursor materials, the cordierite precursor materials comprising 41.8-42.9 wt% of talc, 15.2-31.9 wt.% of at least one hydrated clay, 18.7-27.2 wt% of alumina, and 6.5-15.8 wt% of silica, and 3-10 wt% of at least one binder, the batch material being free of calcined clay; and forming the green ceramic batch material into the green ceramic body. The green ceramic body does not contain the calcined clay but has a honeycomb structure. The honeycomb structure comprises a web structure that has a plurality of cell walls, and 90% of the web structure is free of fast flow webs.
【課題】 高速流ウェブを減少させる。【解決手段】 ４１．８重量％〜４２．９重量％のタルク、１５．２重量％〜３１．９重量％の少なくとも１種類の水和粘土、１８．７重量％〜２７．２重量％のアルミナ、および６．５重量％〜１５．８重量％のシリカを含むコージエライト前駆体材料と、３重量％〜１０重量％の少なくとも１種類の結合剤とを含む、焼成粘土を含まない未焼成セラミックバッチ材料を用意し、用意した未焼成セラミックバッチ材料をセラミック未焼成体に成形する、各工程を有するセラミック未焼成体を製造する方法であって、セラミック未焼成体が焼成粘土を含まず、セラミック未焼成体がハニカム構造を有し、ハニカム構造が複数のセル壁を備えたウェブ構造を有し、ウェブ構造の９０％に高速流ウェブが存在しない。【選択図】 なし
