実験手順
In order to remove the excess yttrium oxide and phosphoric acid from the solids in the slurry, a small amount of an inorganic acid is added to the slurry. The acid releases the yttrium compound and phosphoric acid from the yttrium phosphate and allows them to react on their own until the phosphoric acid is consumed. The 1.5 molar percent excess of the yttrium compound reacts with the acid to form a soluble yttrium salt which dissolves in the aqueous phase of the slurry. When yttrium oxide is used as the yttrium compound and nitric acid is used as the inorganic acid, the reaction provides soluble yttrium nitrate which combines with the remaining phosphoric acid to produce yttrium phosphate solids and with minor amounts of yttrium nitrate in solution.
