Hematite in Oil Drilling Applications African Pegmatite

Hematite (red iron oxide) is an oxide and ore of iron, bearing the chemical formula Fe 2 O 3, and a hardness of 5.5 to 6.5 on the Mohs scale.Its major use is as a source of iron for the production of that metal and of steel. Due to its hardness, high natural purity, abundance and low price, hematite has found increasing uses in fields removed from smelting, such as oil and gas production and

Hematite (α-Fe2O3) pure and doped with Eu3+

2020-11-1  The α-Fe 2 O 3:Eu 3+ powders were prepared by high-energy ball milling using Fe(OO)H and Eu 2 O 3 as raw materials. The Fe(OO)H and Eu 2 O 3 powders were subjected to dry milling for 15, 30 and 45 h. The Rietveld refinements results showed that after 45 h of milling the materials obtained were α-Fe 2 O 3 with 100 wt.% purity for the sample without Eu 2 O 3, and 98.25 wt.% and 93.82
