It occurs naturally as the mineral hematite which is mined as the main ore of iron. Α-Fe 2O 3 has the rhombohedral, corundum (α-Al 2O 3) structure and is the most common form. In the γ polymorph, some of the Fe sit on tetrahedral sites, with four oxygen ligands. That is, each Fe center is bound to six oxygen ligands. In the main one, α, iron adopts octahedral coordination geometry.

Structure įe 2O 3 can be obtained in various polymorphs. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition however, in chemistry, rust is considered an ill-defined material, described as Hydrous ferric oxide. As the mineral known as hematite, Fe 2O 3 is the main source of iron for the steel industry. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare and iron(II,III) oxide (Fe 3O 4), which also occurs naturally as the mineral magnetite. Look around and you may be able to find a discount on Steam, Humble Bundle, or the storefront of your choice.Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2O 3. Thankfully, it tends to go on sale quite often. If you want to play it, you’ll have to fork over some cash. In short, Rust is not a free-to-play game. It’s also unclear whether or not PS5 and Xbox Series X|S version of Rust are in the works. However, without definitive launch plans in sight, it’s unclear how much these console versions of the game will cost. PlayStation 4 and Xbox One versions are planned, and those copies should work fine on current-generation platforms. Unfortunately, the game was delayed in late 2020, and is now looking at a vague 2021 release window.

Rust is supposed to be coming to consoles, too. Even better, the game often goes on sale, or can be found discounted at places such as Humble Bundle. However, the price for Rust is set at just $40. Modern games tend to launch around $60, or even higher for some current-generation releases. While Rust is definitely not free-to-play, it is at least a bit cheaper than most triple-A releases.
