Product Description

Nitrgoen Silane Semiconductor Appliction CAS No. 7803-62-5

 

Description:

 

The silane produced by this route can be thermally decomposed to produce high-purity silicon and hydrogen in a single pass.

 

Still other industrial routes to silane involve reduction of SiF4 with sodium hydride (NaH) or reduction of SiCl4 with lithium aluminum hydride (LiAlH4).

 

Another commercial production of silane involves reduction of silicon dioxide (SiO2) under Al and H2 gas in a mixture of NaCl and aluminum chloride (AlCl3) at high pressures:

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.
