実験手順
The lanthanum and terbium raw materials may be lanthanum oxide and terbium oxide. Lanthanum oxide is added to concentrated nitric acid to form lanthanum nitrate, which is then preferably diluted. Terbium oxide is added to concentrated nitric acid to form terbium nitrate solution, which is then preferably diluted. The diluted lanthanum nitrate solution and the diluted terbium nitrate solution are then combined to form a single rare earth solution. Hydrated cerium nitrate is then added to the rare earth solution. The molar ratio of the rare earth elements in the rare earth solution is thus about x mole La:y mole Ce:z mole Tb where x=0.39 to 0.73, y=0.17 to 0.45 and z=0.10 to 0.17. The molar ratio of the rare earth elements is preferably about 0.6 mole La:0.225 mole Ce:0.165 mole Tb.
