      Product Detail  


    Product Name: Dichlorosilane (DCS)
    Chemical Formula: SiH₂Cl₂
    CAS Number: 4109-96-0

    Physical Properties

    • Appearance: Colorless gas with a pungent, irritating odor.
    • Molecular Weight: 100.98 g/mol.
    • Boiling Point: Approximately 8 °C (46 °F). Due to this low boiling point, it is typically stored and transported as a compressed liquefied gas or dissolved in an appropriate solvent.
    • Density: Heavier than air; the vapor can accumulate in low-lying areas, posing a hazard.
    • Solubility: Reacts with water but is soluble in various organic solvents.

    Chemical Properties

    • High Reactivity & Flammability: DCS is highly flammable and pyrophoric (can ignite spontaneously upon contact with air). Its wide flammability range makes it extremely hazardous.
    • Moisture Sensitivity: It reacts violently with water or moisture in the air, releasing hydrogen chloride (HCl) gas and forming siloxanes. This makes it highly corrosive to metals and tissues.
    • Thermal Decomposition: At elevated temperatures, DCS readily decomposes into elemental silicon, hydrogen chloride, and hydrogen gas, making it ideal for chemical vapor deposition processes.

    Key Applications

    • Semiconductor Manufacturing: This is the most critical application. DCS is extensively used in Chemical Vapor Deposition (CVD) and Epitaxy to deposit high-quality silicon-based thin films. It allows for lower deposition temperatures compared to silane, resulting in superior film uniformity, fewer defects, and excellent step coverage.
    • Advanced Materials & Coatings: Used in the production of silicon nitride, silicon dioxide, and polysilicon layers for integrated circuits, memory devices, and solar cells.
    • Optoelectronics: Serves as a precursor material in the manufacturing of optical fibers and optoelectronic components.
    • Surface Modification: Applied in surface treatment processes to improve adhesion, alter surface energy, and provide protective coatings on glass, metals, and polymers.

    Appearance:

    Dichlorosilane is a flammable and poisonous gas, with a strong repulsive odor. It is easily ignited in air, reacts with oxidizing agents, is very toxic by inhalation, and is a strong irritant to skin, eyes and mucous membranes. Under prolonged exposure to fire or intense heat the container may rupture violently or rocket.

    Air and Water Reactions:

    Highly flammable. Based on the properties of similar materials, there is the possibility that the reaction of this compound with water may be vigorous or violent. Products of the reaction include hydrogen chloride. The reaction generates heat and this heat may be sufficient to ignite the product. The chlorosilicon hydrides(ClxSiHy) are spontaneously flammable in air, NFPA 1991.

    Reactive Group:

    Chlorosilanes

    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.

    Physical Dangers:

    The gas is heavier than air and may travel along the ground; distant ignition possible.
