Aluminium Selenide is a high-purity, white to gray crystalline compound with excellent reactivity and thermal stability, commonly used in semiconductor and optoelectronic applications. It is a typical ionic compound that hydrolyzes in the presence of moisture, releasing toxic hydrogen selenide (H₂Se) gas.
Our Al₂Se₃ granules are manufactured with a typical purity of ≥99.99%, ensuring minimal contamination and consistent quality. We also offer comprehensive after-sales support—please feel free to contact us if you have any questions.
