[0082] Advantages and embodiments of this invention are further illustrated by the following examples, but the particular materials and amounts thereof recited in these examples, as well as other conditions and details, should not be construed to unduly limit this invention. In these examples, all percentages, ratios and ratios are by weight unless otherwise indicated.
[0083] These abbreviations are used in the following examples: g = gram, h = hour, min = minute, mol = mole, mL = milliliter, L = liter, MHz = megahertz, MPa = megapascal, psig = pound per square inch pressure. Chemicals were obtained from Sigma-Aldrich (St. Louis, MO) if not stated otherwise.
[0084] Material
[0085]
[0086]
[0087] Latex C preparation
[0088]Latex C was prepared as follows: 52 kg of water, 80 g of potassium phosphate buffer dissolved in an additional 500 g of water, and 40 g of ammonium persulfate dissolved in an additional 500 g of water were added to an 80 L reactor. The...
example 1
[0098] Example 1 (EX1)
[0099] To 141.84 g of diluted (23.5% solids by weight) zirconia sol #2 was added dropwise 549.69 g of Latex B over 35 minutes while using a Laboratory Disperserator 2000 Series Model 90 (Premier Mills Inc., Exton, PA, USA). (Premier Mill, Exton, PA)) driven Cowles blades were mixed at medium speed. A dense foam containing solids formed. After all the latex had been added, the mixture was stirred at high speed for 28 minutes. Let the mixture sit for 27 minutes, then filter the liquid through gauze and return the solids to the container. Add approximately 500 mL of hot deionized water as the first rinse. The filtration and rinsing process was repeated two more times. After the final rinse, the solids were squeezed dry by hand and placed in a batch oven at 100°C for 16 hours. The process yielded 172.3 g of material (86.15% yield).
example 2
[0100] Example 2 (EX2)
[0101] 60.6 g of alumina sol (30% by weight solids) was added dropwise to 594.18 g of Latex C within 2 minutes while using a Laboratory Disperserator 2000 Series 90 (Premier Mill, Exton, Pennsylvania, USA). Exton, PA)) driven Cowles blades were agitated at medium speed (VARIAC setting 20). A crumb slurry mixture is formed. The mixture was stirred for another 2 minutes, then allowed to stand for 5 minutes. Strain the liquid through gauze. As described in Example 1 but the solids were washed three times with cold deionized water, then hand squeezed and placed in a batch oven at 106°C for 16 hours.
