Method for calcining kaolin
A method for improving brightness in a calcined kaolin pigment while minimizing detrimental effects on abrasiveness. The kaolin calciner feed is intermixed with a particulate material which is oxidizable during calcining to provide a source of auxiliary thermal energy in the kaolin bed; and the mixt...

| description | A method for improving brightness in a calcined kaolin pigment while minimizing detrimental effects on abrasiveness. The kaolin calciner feed is intermixed with a particulate material which is oxidizable during calcining to provide a source of auxiliary thermal energy in the kaolin bed; and the mixture is calcined at a temperature in the range of about 900 DEG C., but below about 1100 DEG C., and in the presence of an oxidizing atmosphere throughout the calcining step. |
