What are the characteristics of selenide?

Selenide properties Selenides are compounds containing selenium anions. Similar to sulfides, Se2- can only exist in strong alkaline solutions. In neutral solutions, it is HSe-, while in acid solutions, H2Se is formed. There are some selenides that easily react with oxygen in the air, and metal selenides are easier to decompose than sulfides. Active metal selenide is prone to oxidation or dissolves reaction. Aluminum selenide can be oxidized in moist air and dissolves rapidly, releasing highly toxic dissolve selenide gas.
Existing forms of selenide minerals
Pure selenide minerals are rare, and most of them co-exist with sulfide minerals. The minerals of selenide include white selenite and red selenite. Polyselenide is a compound containing Sen2- anion. They can be obtained by eutecticizing the corresponding elements in a quartz tube.

What are the types of selenide powder ?
Tongrun provides you with antimony selenide Sb2Se3, tungsten selenide WSe2, gallium selenide Ga2Se3, copper selenide Cu2Se, indium selenide In2Se3, cadmium selenide CdSe, zinc selenide ZnSe and other types of powder.

Is selenide poisonous?
Selenium is an antagonist of some toxic substances. It has the function of detoxifying heavy metals such as mercury, lead, cadmium, etc., can eliminate a variety of harmful free radicals in the body, reduce or delay the production of lipofuscin, have anti-cell aging effects, and promote the human body to iodine Absorption and organization. However, excessive intake of inorganic selenium will definitely cause toxic conditions such as hair loss and rotten nails. How to extinguish a selenide fire? When cyanide, selenide, and phosphide catch fire, you can’t use them to put out the fire, you can only use water mist or carbon dioxide to put out the fire.

Bismuth selenide: a new material leading the revolution of semiconductors
The researchers used bismuth selenide. In addition, they used a thin film deposition technique called “sputtering,” which is driven by the momentum exchange between ions and atoms in the target material. Although common in the semiconductor industry, this is the first time that sputtering technology has been used to make topological insulator materials that can be used in the semiconductor and magnetic materials industries. Nanoparticles are smaller than 6nm in the topological insulating layer produced by sputtering create new physical properties for the material-changing the behavior of electrons in the material. The researchers found that compared with existing materials, this material is 18 times more efficient in computational processing and memory.
