Kaʻina 1: E hoʻoulu i ka lumi wela, e hoʻohui i ka solution sodium hydroxide o 5.0mol/L i ka cerium sulfate solution o 0.1mol/L, e hoʻoponopono i ka waiwai o ka pH i ʻoi aku ka nui ma mua o 10, a hiki i ka hopena o ka ua.Pumi ʻia ka sediment, holoi pinepine me ka wai deionized, a laila maloʻo i loko o ka umu 90 ℃ no 24 mau hola.Ma hope o ka wili ʻana a me ka kānana ʻana (ʻoi aku ka nui o ka ʻāpana ma lalo o 0.1mm), loaʻa ka cerium oxide a waiho ʻia i kahi maloʻo no ka mālama ʻana i ka sila.Ka Papa Hana 2: Lawe i ka cerium chloride a i ʻole cerium nitrate ma ke ʻano he kumu, hoʻololi i ka waiwai pH i 2 me ka wai amonia, hoʻohui i ka oxalate e hoʻoheheʻe i ka cerium oxalate, ma hope o ka hoʻomehana ʻana, hoʻōla, hoʻokaʻawale a holoi, hoʻomaloʻo ma 110 ℃, a laila puhi i ka cerium oxide ma 900 ~ 1000 ℃.Hiki ke loaʻa ka Cerium oxide ma ka hoʻomehana ʻana i ka hui ʻana o ka cerium oxide a me ka pauka kalapona ma 1250 ℃ ma kahi lewa o ka carbon monoxide.
