Abstract: A mixture for making a ceramic article includes a ceramic forming component, a liquid vehicle, a cellulosic binder, and a stabilizer comprising an acetate salt. The disclosure also provides a method of making the ceramic article including extruding the mixture to form a ceramic green body, drying the ceramic green body to remove at least a portion of the liquid vehicle, and optionally firing to form the ceramic article. The ceramic green body possesses excellent strength and excellent skin properties without increasing the organic load or the addition of hydrated clays.

Abstract: A method of reducing the defects in ceramic articles and precursors, particularly ceramic articles and precursors made using a batch composition containing an oil phase material. The method includes increasing the concentration of a water insoluble soap in the batch composition, which can increase the cohesive strength of the oil phase, leading to a reduction in the incidence of defects in the ceramic articles and precursors.

Abstract: A method of manufacturing a porous ceramic article is provided that includes injecting a gas into a precursor batch material. The gas is pressurized to a positive gauge pressure. Exemplary gasses that can be injected into the precursor batch material include at least one of nitrogen, helium, neon, argon, krypton, and xenon. Air can also be injected into the precursor batch material, including air in which at least a portion of CO2 and/or O2 naturally occurring in air has been removed.

Abstract: A method for producing a ceramic article comprising the steps of providing a plasticized ceramic precursor batch composition comprising an inorganic ceramic powder batch composition; a liquid vehicle; and an organic binder system comprising at least one organic lubricant grafted to a cellulose ether binder. An extruded green body can be formed from the plasticized ceramic precursor batch composition and subsequently fired under conditions effective to convert the extruded green body into a unitary ceramic article. Also provided are ceramic articles manufactured by the methods disclosed herein.
