| Reactivity Alerts | Highly Flammable |
| Reactivity Profile | Chlorosilanes, such as DICHLOROSILANE, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. |
| Chemical Dangers | The substance may ignite spontaneously on contact with air. Decomposes on heating and on burning. This produces toxic fumes including hydrogen chloride. Reacts with water and moist air. This produces hydrogen chloride. Attacks many metals in the presence of water. |

용도
개요
Dichlorosilane is a highly flammable, corrosive, and toxic gas at room temperature and atmospheric pressure. It causes severe bums on contact with eyes, skin, and mucous membranes. With water or moisture, it hydrolyzes rapidly to yield silica and silicon oxyhydride along with hydrochloric acid. It is shipped as a liquefied gas in low pressure cylinders at its vapor pressure of 9.1 psig (62.7 kPa) at 70°F (21.1℃. It can form flammable mixtures with air and oxidizing agents.
용도
Dichlorosilane is primarily used in the electronics industry for such applications as growth of epitaxial or polycrystalline silicon and chemical vapor deposition of silicon dioxide and silicon nitride.
