Only the nonmetals oxygenand silicon are found in greater abundance. Aluminum oxide (Al2O3) is the fourth mostabundant compound found on Earth, with a weight of 69,900 ppm. Another alum-typecompound is potassium aluminum sulfate [KAl(SO4)2?12H2O]. Although aluminum is notfound in its ...
Aluminum compounds which have been found satisfactory include aluminum sulphate, aluminum nitrate, and aluminum chloride, as well as various aluminates including sodium aluminate and potassium aluminate. Since the aluminates are highly alkaline, it will be necessary in such cases to acidify the slurry...
