Ultra High Purity Solar Battery Gas CAS No. 7803-62-5
Description:
For classroom demonstrations, silane can be produced by heating sand with magnesium powder to produce magnesium silicide (Mg2Si), then pouring the mixture into hydrochloric acid. The magnesium silicide reacts with the acid to produce silane gas, which burns on contact with air and produces tiny explosions. This may be classified as a heterogeneous[clarification needed] acid-base chemical reaction since the isolated Si4 − ion in the Mg2Si antifluorite structure can serve as a Brønsted–Lowry base capable of accepting four protons. It can be written as:
4 HCl + Mg2Si → SiH4 + 2 MgCl2

4. Applications:
Several industrial and medical applications exist for silane and functionalized silanes.
| 1 | silanes are used as coupling agents to adhere fibers such as glass fibers and carbon fibers to certain polymer matrices, stabilizing the composite material. |
| 2 | They can also be used to couple a bio-inert layer on a titanium implant. |
| 3 | Other applications include water repellents, masonry protection, control of graffiti, applying polycrystalline silicon layers on silicon wafers when manufacturing semiconductors, and sealants. |
| 4 | Silane is also used in supersonic combustion ramjets to initiate combustion in the compressed air stream. As it can burn using carbon dioxide as an oxidizer it is a candidate fuel for engines operating on Mars. |
| 5 | Silane and similar compounds containing Si—H bonds are used as reducing agents in organic and organometallic chemistry. |
| 6 | Silane methacrylates are used in dentistry as part of tooth-colored, composite filling material. Silane methacrylates act as a coupling agent between the hard, silicate-based, ceramic filler and the organic, resin-based oligomer matrix. |
