CERAMIC BATCH MIXTURES HAVING DECREASED WALL DRAG

Abstract:

According to embodiments, a batch mixture includes inorganic components, a non-polar carbon chain lubricant, and an organic surfactant having a polar head. The non-polar carbon chain lubricant and the organic surfactant are present in concentrations satisfying the relationship: B(C.sub.1(d+d.sub.0)+C.sub.2(f+f.sub.0))=SC, where: d.sub.0+d is an amount of non-polar carbon chain lubricant in percent by weight of the inorganic components, by super addition; f.sub.0+f is an amount of organic surfactant in percent by weight of the inorganic components, by super addition; B is a scaling factor; C.sub.1 is a scaling factor of the concentration of the non-polar carbon chain lubricant; and C.sub.2 is a scaling factor of the concentration of the organic surfactant.
