product description

Products Description of Trichlorosilane CAS#10025-78-2

Trichlorosilane is a highly flammable, volatile liquid with a pungent odor, posing fire/explosion risks even below -18 °C. It reacts violently with water, alkalis and oxidizers, decomposes at 900 °C into toxic fumes, and forms explosive air mixtures. It reacts with acetylene/hydrocarbons and can be reduced to silane. Soluble in organic solvents; anhydrous form is non-corrosive to iron/stainless steel but corrosive to most metals when moist.


Product Applications of Trichlorosilane CAS#10025-78-2

Trichlorosilane is the primary precursor for polysilicon and organosilicon polymer production, with additional use in industrial instrumentation.
