METHOD FOR POROUS CERAMIC HONEYCOMB SHRINKAGE REDUCTION
A method for reducing shrinkage variability of ceramic honeycombs formed from batch mixtures including inorganic materials and a pore former. X is a cumulative amount of pore former particles having a diameter less than 37 µm. There is a maximum value of X (Xmax) and a minimum value of X (Xmin) duri...

| description | A method for reducing shrinkage variability of ceramic honeycombs formed from batch mixtures including inorganic materials and a pore former. X is a cumulative amount of pore former particles having a diameter less than 37 µm. There is a maximum value of X (Xmax) and a minimum value of X (Xmin) during a production period, and ?X= Xmax-Xmin. The method fixes an amount of pore former fines such that X ranges from 25%-71% by volume, and ?X is = 23% throughout the production period.
La présente invention concerne un procédé de réduction de variabilité de retrait des nids d'abeilles en céramique formés à partir de compositions comprenant des matériaux non organiques et un porogène. X est la valeur cumulée de particules porogènes présentant un diamètre inférieur à 37 µm. Il existe une valeur maximale de X (Xmax) et une valeur minimale de X (Xmin) au cours d'une période de production, et ?X = Xmax - Xmin. Le procédé fixe une quantité de particules fines porogènes telle que X vaille de 25 % à 71 % par volume, et ?X soit = 23 % pendant toute la période de production. |
