About Magnesium silicide, ≥99% trace metals basis, -20 mesh

Magnesium silicide (CAS 22831-39-6) is an electronic material offered by Vaqora Chemicals with a typical assay of ≥99%. Its molecular formula is Mg2Si and its molecular weight is 76.7 g/mol. Common synonyms include Dimagnesium silicide and Magnesium silicide (Mg2Si).

It is supplied as a grey to very dark grey and grey blue powder. Key physical data: a melting point of 1102 °C and a boiling point of 116 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include semiconductor research, electronic devices and thin films. Buyers come mainly from academic and industrial research and electronics and semiconductors.

Available in 10 g and 25 g packs, Magnesium silicide is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
