Selenide properties Selenides are compounds that contain selenium ions. Se2- is similar to sulfides in that it can only exist when strong alkaline solution exists. In neutral solution, HSe+ is formed, whereas in acidic solution, H2Se. Some selenides easily react with air oxygen, while metal selenides dissolve more easily than sulfides. Metal selenides that are active are prone to oxidation, or dissolves reactions. Aluminum selenide can oxidize in moist atmosphere and dissolve rapidly, releasing toxic dissolve selenide gases.
Selenide minerals: types and forms
Selenide minerals co-exist in most cases with sulfide mineral. Selenide minerals include white and red selenite. Polyselenide, a compound that contains the Sen2- anion, is called polyselenide. These compounds can be made by eutecticizing elements in quartz tubes.

What are the different types of selenide? powder ?
Tongrun can provide you with powders such as antimony selenide.

Is selenide poisonous?
Selenium acts as an antagonist to some toxic substances. It detoxifies heavy metals, such as mercury and lead. It can also reduce or delay lipofuscin production, slow down the aging of cells, and help the human body to absorb and organize iodine. However, an excessive intake of selenium inorganic will cause toxic conditions including hair loss and decayed nails. How to put out a selenide flame? If cyanide or selenide catches fire, it can’t be put out with water mist, only carbon dioxide.

Bismuth Selenide: A new material that is leading the revolution in semiconductors
The researchers used Bismuth Selenide. The researchers also used “sputtering,” a thin film depositing technique that is powered by the momentum of ions and atoms within the target material. It is the very first time sputtering has been used for topological insulator material that can be used by the magnetic and semiconductor materials industries. Sputtering produces nanoparticles that are smaller than six nanometers. This layer changes the behavior and physical properties of the material. The researchers discovered that this material has 18 times the efficiency of existing materials for computing processing and memory.
