ABSTRACT:
A process for preparing a composite particulate material, comprising the steps of providing a particulate primary material having a primary softening temperature; providing a particulate support material having a support softening temperature; providing a particulate binder material having a softening temperature which is less than the primary softening temperature and the support softening temperature; mixing the primary material, the support material and the binder material so as to provide a substantially uniform mixture; and heating the mixture to a temperature greater than or equal to the softening temperature of the binder material and less than the primary softening temperature and the support softening temperature, whereby the binder material binds the primary material to the support material so as to provide a composite particulate material.
