1. Properties
SiH4 (Silane/Silic Hydride) is a colorless, flammable gas. Silane is flammable at temperatures below 54 °C (130 °F).
2. Application
Silane is used as a binder to adhere fibers such as glass fiber and carbon fiber to some polymeric polymers, stabilizes composite materials, used to graft a bioinert layer on a titanium implant.
Other applications include waterproofing, masonry protection, graffiti control, application of polycrystalline silicon layers on silicon wafers when manufacturing semiconductors and sealants. In ultrasonic furnaces, Silane is used to initiate combustion in a compressed air stream because it can be ignited using carbon dioxide as an oxidant. Silane is a candidate fuel for engines operating on Mars.

- Use Chlorine Acid to Control and Neutralize PH. Acid HCl can be used to adjust the basicity of the solution. In industries requiring purity (food, pharmaceutical, drinking water), high quality hydrochloric acid is used to adjust the pH of the water to be treated. In industries that do not require high purity, industrial quality HCL Acid is just enough to neutralize wastewater and treat pool water.
- Use hydrochloric acid to regenerate by ion exchange. High quality HCl acid is used to regenerate ion exchange resins. Cation exchange is widely used to remove ions such as Na+ and Ca2+ from aqueous solutions, producing demineralized water. This acid is used to wash cations from resins. Ion exchangers and demineralized water are used in all chemical industries, drinking water production, and some food industries.
