Abstract
The composition of this invention is an inorganic oxide particulate comprising at least 10% by weight organic material in which the particulate has an auto-ignition temperature which is at least 20° C. higher than the auto-ignition temperature of the particulate and organic material which does not contain antioxidant and/or inhibitor. Accordingly, a method has been developed in which one is able to elevate the auto-ignition temperature of such organic containing particulates. In a preferred embodiment the method comprises including antioxidant or inhibitor in the organic material prior to combining it with the inorganic oxide.
