Aluminum selenide powder is a high-purity, fine crystalline material featuring high reactivity and excellent thermal properties, making it highly suitable for advanced semiconductor and optoelectronic applications. It is a typical ionic compound that readily hydrolyzes in the presence of moisture, producing toxic hydrogen selenide (H₂Se) gas. The powder form offers enhanced surface area and reactivity, especially beneficial in precision chemical reactions and thin-film fabrication processes.
Our Al₂Se₃ powder is produced with a purity level of ≥99.99%, ensuring extremely low levels of metallic and non-metallic impurities. We also offer comprehensive after-sales support—please feel free to contact us if you have any questions.
