Selenium powder
It is a chemical with the atomic number and symbol Se. It is nonmetal, but it’s more commonly called a metalloid. It has properties intermediate between elements below and above in the periodic tables, such as 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 powder or grain form. It is usually a powder with a uniform color and a consistent appearance.
Selenium Application
Selenium Selenium is a by-product of the refining process for metal sulfide, and it can replace sulfur in some cases. 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 a variety of multivitamins as well other dietary supplements as well infant formula. It’s also found as a component to the antioxidant enzymes thioredoxin reductiontase as well as glutathione-peroxidase which reduce certain oxidized molecule in animals and some plant species. Selenium needs in plants vary by species. Some require large amounts of the element, while others appear to need none.
Selenium powder preparation
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 (LTORL), 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. After the solid-liquid separator, use H2O2 for the oxidant. Adjust the pH of the solution to separate the selenium from the tellurium. Reduce selenium with Na2SO3 and hydrochloric acid. Selenium and tellurium recover at 99% each. Purity can be as high as 99%.
Selenium powder Toxicity
Inhalation causes bronchial inflammation as well as pulmonary edema and selenium-containing compounds. Elemental Selenium powder Exposure can also cause mucous membrane inflammation, nose bleeding, and coughing.
