Silane , SiH4 , Ultra High Silane 99.5% - 99.9999% Used For Semiconductor
Description:
In general, the alkaline-earth metals form silicides with the following stoichiometries: MII2Si, MIISi, and MIISi2. In all cases, these substances react with Brønsted–Lowry acids to produce some type of hydride of silicon that is dependent on the Si anion connectivity in the silicide. The possible products include SiH4 and/or higher molecules in the homologous series SinH2n+2, a polymeric silicon hydride, or a silicic acid. Hence, MIISi with their zigzag chains of Si2 − anions (containing two lone pairs of electrons on each Si anion that can accept protons) yield the polymeric hydride (SiH2)x.
Yet another small-scale route for the production of silane is from the action of sodium amalgam on dichlorosilane, SiH2Cl2, to yield monosilane along with some yellow polymerized silicon hydride (SiH)x.

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. |
