A method for heating ware in a kiln. The ware space of the kiln includes a plurality of temperature control zones oriented in a first direction, and a plurality of temperature control zones oriented in a second direction. The method includes heating the ware space in a first heating stage, a second heating stage, and a third heating stage. At least one of the following conditions is satisfied: (i) in one of the heating stages, a temperature control zone oriented in the first direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the first direction; and (ii) in one of the heating stages, one temperature control zone oriented in the second direction has a setpoint temperature that is different from a setpoint temperature of one other temperature control zone oriented in the second direction.

A method for fabricating ceramic honeycomb structural bodies that includes conveying at least one green honeycomb structural body of a first type and at least one green honeycomb structural body of a second type through a kiln in a manner which reduces cracking or fissures in the fired objects.

A method for fabricating a green ceramic article containing organic compounds. The method involves first heating the green ceramic article to sequentially remove the organic compounds such that the organic compound with the lowest weight loss onset temperature is substantially removed prior to the next higher weight loss onset temperature organic compound. The organic compounds include but are not limited to at least an oil or oil-based compound having a flash point or an ignition temperature, higher than the weight loss onset temperature. For this system the temperature during heating is maintained below the flash point of the oil or oil-based compound until substantial removal thereof from the green ceramic structural body. After the organic compounds are substantially removed, the green ceramic article is further fired to a temperature and for a time to obtain a final fired body.

A method for forming and shaping powder mixtures involves compounding, homogenizing, and plasticizing components to form a mixture. The components are powder materials, binder, solvent for the binder, surfactant, and non-solvent with respect to at least the binder, the solvent, and the powder materials. The non-solvent is lower in viscosity than the binder combined with the solvent. The components are chosen to result in improved wet green strength in the subsequently formed green body. The compounding is done by the steps of dry-mixing the powder material, surfactant and binder to form a uniform blend, adding the solvent to the resulting dry blend, and thereafter adding the non-solvent to the blend. The mixture is shaped by passing it through a low to moderate shear extruder, and then through a die to form a green body. The compounding and shaping steps are carried out at a temperature of no greater than ambient temperature. The method is especially suitable for RAM extrusion. Among the advantages, the method results in higher extrusion velocity, throughputs, and wet green strength, without increasing pressures and torques.
