Selenium powder
It is a chemical with atomic numbers 34 and the symbol Se. It is nonmetal, but it’s more commonly called a metalloid. It has properties that are in between sulfur and tellurium on the periodic table. 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 usually a powder with a uniform color and a consistent appearance.
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 mainly in glassmaking and pigments. 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 many multivitamins as well other dietary supplement, infant formula and as a component to the antioxidant enzymes thioredoxin reductiontase or glutathione-peroxidase which reduces oxidized molecules indirectly in animals and certain plants. Selenium needs in plants vary by species. Some require large amounts of the element, while others appear to need none.
Preparation with 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 electrolytic 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 (LTOLL), dilute sulfuric acid-leaching etc. Selenium and tellurium reduction is mainly carried out by copper and sulfur dioxide reduction. method. Pre-roasting & oxidation results in more complex equipment, higher maintenance costs, sulfur dioxide gas that is harmful to humans and the environment and lower recovery rates and purity. Using H2O2 for the oxidant in a weak acid, oxidize both selenium & tellurium. Adjust the pH after the solid-liquid separaton to separate the two elements. Reduce selenium & tellurium using Na2SO3 and hydrochloric acid. Selenium and tellurium recover at 99% each. Purity can be as high as 99%.
Selenium powder Toxicity
Inhalation causes bronchial irritation, edema and pneumonia. Elemental Selenium powder Exposure can also cause mucous membrane inflammation, nose bleeding, and coughing.
