Selenium powder
It is a chemical with the symbol Se, and an atomic number of 34. It is nonmetal, but it’s more commonly called a metalloid. It has properties that are in between the elements below and above the periodic table: sulfur and tellurium. It is rare to find it in its pure ore compound form in the Earth’s crust.
Selenium powder
Water and ethanol are insoluble. Selenium powder can be in granular or powder form. It is pure, has uniform color, high purity (up to 99.99%), and is free of impurities like soil.
Selenium Application
Selenium Selenium is found in metal sulfur ores where it partly replaces the sulfur. Selenium is most often produced commercially as a byproduct during the refining and production of metal sulfide ores. Selenate or pure selenide compounds are rare but known minerals. Selenium is used primarily in glassmaking, and as a pigment. Selenium can be used as a photocell and semiconductor. The silicon semiconductor has replaced most of the electronic applications, which were once very important. In some types of DC power surge protecters and in one type of fluorescent quantum dot, selenium is still used.
Selenium is toxic at even low doses. This can lead to selenosis. Selenium appears in multivitamins as well other dietary supplement, infant formula and as a component to antioxidant enzymes such as glutathione-peroxidase or thioredoxin-reductase. These enzymes reduce oxidized molecules indirectly in animals and certain plants, as well three deiodinase. Selenium needs in plants vary by species. Some require large amounts of the element, while others appear to need none.
Preparation of Selenium Powder
Selenium is an element that is rare. No independent selenium plant exists in the world. Selenium is generally associated with the electrolysis and nickel in the anode-mud. Selenium and tellurium are recovered and purified using many different methods. These include caustic oxidative pressurized leaching (COPL), oxidative roasteding and high temperature leaching (OHTL), low-temperature roasting with oxidative leaching (LTOTL), dilute sulfuric acid-leaching etc. Selenium and tellurium reduction is mainly carried out by copper and sulfur dioxide reduction. method. Pre-roasting oxidation is a more complex method that increases the cost and complexity of the power equipment. In addition, sulfur dioxide gas can be harmful to humans and the environment. The H2O2 is used as an oxidant to oxidize selenium. Tellurium can be separated by adjusting the pH after the solid-liquid separation. Selenium and tellurium recover at 99% each. Purity can be as high as 99%.
Selenium powder Toxicity
Inhalation causes bronchial edema, respiratory membrane irritation and pneumonia. Elemental Selenium powder Exposure can also cause mucous membrane inflammation, nose bleeding, and coughing.
