Synthetic nzira

1. Dissolve lanthanum oxide mu hydrochloric acid nemakemikari nzira uye kuderedza ku100-150g / L (yakaverengwa seLa2O3).Pisa mhinduro kusvika 70-80 ℃, uye wozonaya ne48% hydrofluoric acid.Kunaya kunogezwa, kusefa, kuomeswa, kupwanywa, uye vacuum dehydrated kuti uwane lanthanum fluoride.

2. Isa LaCl3 solution ine hydrochloric acid mundiro yeplatinum uye uwedzere 40% hydrofluoric acid.Dururira mvura yakawandisa uye bvisa yakasara yakaoma.
