Polystyrene sulfonates are a group of medications used to treat high blood potassium. [1] Effects generally take hours to days. [1] They are also used to remove potassium, calcium, and sodium from solutions in technical applications.
Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. This category formerly consisted solely of polystyrene sulfonate, a polyanionic resin attached to a cation, administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels).
Iron powder. Iron powder has several uses; for example production of magnetic alloys and certain types of steels. [1]Iron powder is formed as a whole from several other iron particles.
Various early 20th Century embalming fluids. Embalming chemicals are a variety of preservatives, sanitising and disinfectant agents, and additives used in modern embalming to temporarily prevent decomposition and restore a natural appearance for viewing a body after death.
This composition, usually in a ratio of 5 parts potassium nitrate, to 3 parts aluminum powder, to 2 parts sulfur, is especially popular with hobbyists.
The following processes can be used to produce metal powder: [6] Direct reduction is the result of blending carbon with iron oxide ore, heating the mixture, removing the sponge iron from the carbon, grinding it, annealing it, and regrinding to make the powder form usable for manufacturing.
In electronics, carbonyl iron is used to manufacture magnetic cores for high-frequency coils and in production of some ferrites.Spherical particles manufactured of carbonyl iron are used as a component of the radar absorbing materials used by the military, in stealth vehicles, for example. [3]
Heat-sensitive carbon fiber tubes coated with a UV curable powder coating. Powder coating is a type of coating that is applied as a free-flowing, dry powder.Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
