実験手順

Room temperature deionized water (2600 ml), 48 g of 16N analytical reagent grade nitric acid and 800 g alpha aluminum monohydrate powder sold under the trade designation "Disperal" were charged into an 18.9 liter polyethylene lined steel vessel. The charge was dispersed at high speed for five minutes using a Gifford-Wood Homogenizer Mixer (Greeco Corp., Hudson, N.H.). The resulting dispersion and an aqueous solution containing 35.9% yttrium nitrate hexahydrate were metered through an in-line mixer in an amount to provide the weight of yttrium nitrate solution specified in Table I. The resulting gel was extruded into a 46 cm×66 cm×5 cm polyester lined aluminum tray where it was dried in a forced air oven at 100° C. to a friable solid. The resultant dried material was crushed using a "Braun" type UD pulverizer having a 1.1 mm gap between the steel plates. The crushed material was screened and the 0.125 mm to about 1 mm screen size material was retained for firing.
