Abstract
Official abstract text for this publication.
A method comprising reacting an aluminum mineral polymorph or a gallium mineral polymorph with an acid at an aluminum metal to acid molar ratio or gallium metal to acid molar ratio sufficient to produce M 13 nanoscale clusters, M nano-agglomerates, or a M 13 slurry, wherein M is Al or Ga.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: reacting an aluminum mineral polymorph with an acid at an aluminum metal to acid molar ratio sufficient to produce M 13 nanoscale clusters or M 13 nano-agglomerates, wherein M is Al and the aluminum metal to acid molar ratio is 1:0.7 to 1:1.0 mol eq of metal to acid to produce the nano-agglomerates or 1:1.15 to 1:1.3 mol eq of metal to acid to produce the nanoscale clusters. 2. The method of claim 1 , wherein the aluminum mineral polymorph is selected from corundum, gibbsite, boehmite, diaspore, bayerite, nordstrandite, or any combination or mixture thereof. 3. The method of claim 1 , wherein the acid is selected from nitric acid, sulfuric acid, selenic acid, a halide acid, a sulfonic acid, a carboxylic acid, or a mixture thereof. 4. The method of claim 1 , wherein the acid is nitric acid. 5. The method of claim 1 , wherein the method produces the nano-agglomerates. 6. The method of claim 1 , wherein the method produces the nanoscale clusters. 7. The method of claim 1 , wherein the method is controlled to avoid formation of Al(NO 3 ) 3 . 8. The method of claim 1 , wherein the nanoscale clusters have a dimension ranging from 1 nm to 5 nm. 9. The method of claim 1 , wherein the nano-agglomerates have a dimension ranging from 5 nm to 200 nm. 10. The method of claim 5 , wherein the acid is nitric acid. 11. The method of claim 5 , wherein the aluminum mineral polymorph is selected from corundum, gibbsite, boehmite, diaspore, bayerite, nordstrandite, or any combination or mixture thereof. 12. The method of claim 10 , wherein the aluminum mineral polymorph is selected from corundum, gibbsite, boehmite, diaspore, bayerite, nordstrandite, or any combination or mixture thereof. 13. The method of claim 6 , wherein the acid is nitric acid. 14. The method of claim 6 , wherein the aluminum mineral polymorph is selected from corundum, gibbsite, boehmite, diaspore, bayerite, nordstrandite, or any combination or mixture thereof. 15. The method of claim 13 , wherein the aluminum mineral polymorph is selected from corundum, gibbsite, boehmite, diaspore, bayerite, nordstrandite, or any combination or mixture thereof. 16. The method of claim 1 , wherein the method produces an aqueous M 13 nanoscale clusters solution. 17. The method of claim 1 , wherein the method produces an aqueous M 13 nano-agglomerates solution. 18. A method comprising: reacting an aluminum mineral polymorph with an acid at an aluminum metal to acid molar ratio sufficient to produce M 13 nanoscale clusters, M 13 nano-agglomerates, or a M 13 slurry, wherein M is Al and the aluminum metal to acid molar ratio is greater than 1:0.7 mol eq. of metal to acid to less than or equal 1:1.3 mol. eq. of metal to acid. 19. The method of claim 18 , wherein the aluminum mineral polymorph is selected from corundum, gibbsite, boehmite, diaspore, bayerite, nordstrandite, or any combination or mixture thereof. 20. The method of claim 18 , wherein the acid is selected from nitric acid, sulfuric acid, selenic acid, a halide acid, a sulfonic acid, a carboxylic acid, or a mixture thereof. 21. The method of claim 18 , wherein the acid is nitric acid. 22. The method of claim 19 , wherein the acid is nitric acid.
