Abstract: Green ceramic mixture for extruding into an extruded green body includes one or more inorganic components selected from the group consisting of ceramic ingredients, inorganic ceramic-forming ingredients, and combinations thereof, at least one mineral oil, and from about 0.01 wt % to about 0.45 wt % of an antioxidant based on a total weight of the inorganic component(s), by super addition. The mineral oil has a kinematic viscosity of ≥about 1.9 cSt at 100° C. The at least one antioxidant may have a degradation-rate peak temperature that is greater than the degradation-rate peak temperature of the at least one mineral oil. In some embodiments, the at least one mineral oil includes greater than about 20 wt % alkanes with greater than 20 carbons, based on a total weight of the at least one mineral oil. Methods of making an unfired extruded body using the batch mixture are also disclosed.

Abstract: Methods of firing a cordierite green body to form a fired cordierite body. The green body comprises cordierite-forming raw materials and organic material, the body having a core portion and a skin portion. The green body is pre-heated to a pre-heat temperature that is less than a thermal decomposition temperature of the organic material. The green body is maintained at the pre-heat temperature for a period of time sufficient to minimize a temperature differential between the core portion and the skin portion. The green body is heated to a low firing temperature in a firing atmosphere sufficient to reduce a content of the organic material and to substantially remove chemically bound water from hydrous alumina. The green body is heated to a high firing temperature in a firing atmosphere sufficient to reduce the content of the organic material prior to a substantial removal of chemically bound water from clay.
