Photographic Chemical Formulas - Daniel Devine Photography

The inherent problem of the iron-based silver processes lies in the danger of leaving residual ferric iron in the print, to its eventual undoing as the image is attacked. The Argyrotype process, developed by Mike Ware, has been designed to avert this problem, and ingeniously uses a little known silver salt, silver sulphamate, manufactured 'in ...

Titanium - Essential Chemical Industry

(d) Processing of titanium sponge. As titanium sponge reacts readily with nitrogen and oxygen at high temperatures, the sponge must be processed in a vacuum or an inert atmosphere such as argon. At this stage scrap titanium may be included, and other metals may be added if a titanium alloy is required.

Banded iron formation - Wikipedia

Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age.. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron ...

What Is an Equation for Rust? | Reference

Fe2O3, or rust, is iron oxide formed by a redox reaction of iron and oxygen in the presence of water. Iron is the reducing agent, as it gives up electrons, while oxygen is the oxidizing agent gaining electrons. Simply expressed, Fe plus H2O plus O2 yields Fe2O3.

Corrosion of Iron

The rusting process consists of several steps. In the first step, iron is oxidized to iron(II) ions, Fe2+, and oxygen from the air is reduced to hydroxide ions, OH-. This oxidation-reduction reaction takes place via two separate but simultaneous half-reactions (Equations 1 and 2).
