还原后得到的硫酸亚铁经过净化除杂，滴加到含有适量有机添加剂的沉淀剂NH4OH-NH4HCO3中，沉淀洗涤干燥后900℃煅烧2h，煅烧产品再用稀硝酸和氢氟酸洗涤，得到高纯球形-αFe2O3。

The FeSO_4 obtained by reduction is purified , adding to NH_4OH-NH_4HCO_3 solution containing organic additives , precipitated and finally washed and then calcined at 900 ℃ for 2 hours . The calcined product is washed using dilute nitric acid and hydrofluoric acid , obtaining high-purity α - Fe_2O_3 .
