摘要： The present invention relates to a non-spray-drying, dry-granulation process for making a ceramic particulate mixture comprising from 4 wt % to 9 wt % water, wherein at least 90 wt % of the particles have a particle size of from 80 μm to 600 μm, wherein the process comprises the steps of:



(a) forming a precursor material;
(b) subjecting the precursor material to a compaction step to form a compacted precursor material;
(c) subjecting the compacted precursor material to a crushing step to form a crushed precursor material; and
(d) subjecting the crushed precursor material to at least two air classification steps, wherein one air classification step removes at least a portion of the particles having a particle size of greater than 600 μm from the crushed precursor material, and wherein the other air classification step removes at least a portion of the particles having a particle size of less than 80 μm from the crushed precursor material.

摘要： A porous refractory article including greater than 90 wt % coal combustion fly ash. The coal combustion fly ash is in the form of an interconnected particulate lattice structure, and wherein greater than 50% by volume of the coal combustion fly ash particles within the particulate lattice structure have a particle size of greater than 150 μm. The article has: (a) an apparent porosity of from 30% to 50%, (b) a porosity such that the maximum pore size is less than 500 μm; (c) a cold crushing strength of at least 4.0 MPa; and (d) a thermal conductivity of less than 1.5 W/(m·K).
