High Purity Selenium Se Powder CAS 7782-49-2, 99%

Chemical formula: Se. Black-gray non-metallic. It is soluble in concentrated sulfuric and chloroform. Purity>99% Particle sizes are 200, 100 and 325 mesh.

Selenium can be described as a chemical formula. Selenium metallic dust is dark gray nonmetal. It is easily dissolved in chloroform, concentrated sulfuric acids and carbon disulfide. Selenium metallic powder can be purchased in either granules and powder forms. The powder form has a uniform appearance, with no soil or impurities.

Seenium is a chemical element with the symbol Se. It has anatomic numbers of 34 and 34. It is nonmetal but not considered a metallic element. It's located somewhere between sulfur (on the periodic tables) and tellurium. Selenium can be found in metallic sulfur ore. This partially replaces the role of sulfur. Commercially, selenium can be also used. This is usually a result of the refining these ores. It is possible to obtain selenium compounds, but it is rare to find pure selenium. Glassmaking and pigments are the two main uses of today's selenium. In photovoltaic cells, selenium is also used. Most of the applications once important for electronic products are now obsoleted by silicon-based semiconductor devices. Selenium can still be used to make one kind of fluorescent quantum dots, and many DC power surge protectors.

Even though trace amounts are vital for many cell functions in animals and humans alike, selenium (and especially its salts) can cause toxic reactions in small amounts. Selenium poisoning could occur as a result. Multivitamins often contain selenium which can be dangerous. Selenium can also be found in infant formula and other supplements.

Se powder of Selenium Se CAS 77782-49-2
Red powder, an amorphous version of it, turns to black once you stand. To make vitreous or colloidal forms, it can be heated. It melts at 217degC. After softening at 41degC it becomes amorphous and hardens to 209degC. It will not be found in the natural or pure form of an ore compound. The liquid and concentrated forms of the common alkalies that make it dissolve are nitric acid and liquid nitric. Uses it to create binary alloys such as silver, lead and zinc. It is very low in toxic. Important nutritional factor.

How Was Selenium Powder Se Developed?
Selenium, which is one of the sparse elements in this group, cannot be grown at home. Nickel and selenium are found in the anode for electrolytic anode. Copper electrolytic anode can be purified using a variety of methods, including high-temperature Caustic Oxidation Pressure, dilute Sulfuric Acid Leaching and low temperature oxygen roasting. Copper reduction and sulfur dioxide removal reduce selenium, tellurium, as well as other elements. The factors contributing to the high level of sulfur dioxide gas include pre-roasting, conversion and maintenance of complex power equipment. Because of these factors, both selenium and tellurium can be recovered with high purity. Selenium as well as Tellurium were both reduced to H2O2 by an acidic solution. After liquid seperation, the pH and Selenium were adjusted. The hydrochloric acids acidic treatments by Na2SO3 resulted in the reduction of tellurium. Selenium recovery was 98% & 98% respectively. Both can be purified up to 99%.

Two-part se powder
Selenium can be used in many applications, depending on its purity. Selenium is used for many purposes, including glass and metalworking as well as electronic applications. It is used in the production of selenium dioxide as an electrolytic-manganese-melting catalyst. You can use it as an exposure agent and rectifier.

Storage Selenium powder Condition:
Wet reunion will affect Selenium Sepulption's performance and effects. Vacuum packaging is recommended and powder should be kept dry in cool places. Also, the powder should be kept away from extreme stress.
