Production Description
Se Powder is nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur, and tellurium. Se is found in metal sulfide ores, where it partially replaces the sulfur. Commercially, Se is produced as a byproduct in the refining of these ores, most often during production.

Fertilizers
Researchers found that the application of se fertilizer to lettuce crops decreased the accumulation of lead . Peaches and pears given a foliar Se spray contained higher levels Se and also stayed firm and ripe longer when in storage.
Manganese electrolysis
During the electrowinning of manganese, the addition of Se dioxide decreases the power necessary to operate the electrolysis cells. China is the largest consumer of Se dioxide for this purpose. For every tonne of manganese, an average of 2 kg Se oxide is used.
Glass production
The largest commercial use of Se, accounting for about 50% of consumption, is for the production of glass. Se compounds confer a red color to the glass. This color cancels out the green or yellow tints that arise from iron impurities typical for most glass. For this purpose, various selenite and selenate salts are added. For other applications, a red color may be desired, produced by mixtures of CdSe and CdS.
Alloys
Se is used with bismuth in brasses to replace more toxic lead. The regulation of lead in drinking water applications, such as in the US with the Safe Drinking Water Act of 1974, made a reduction of lead in brass necessary. The new brass is marketed under the name EnviroBrass. Like lead and sulfur, Se improves the machinability of steel at concentrations around 0.15%. Se produces the same machinability improvement in copper alloys.
Lithium-Se batteries
The Li-Se battery is one of the most promising systems for energy storage in the family of lithium batteries. The Li-Se battery is an alternative to the lithium-sulfur battery, with the advantage of high electrical conductivity.
Photoconductors
α-Se thin films have found application as photoconductors in flat panel x-ray detectors. These detectors use α-Se to capture and convert incident x-ray photons directly into electric charge.
