有機硅化合物是含有碳-硅鍵的有機金屬化合物，大多數有機硅化合物與普通有機化合物相似，有機硅化合物一般無色，易燃，疏水且對空氣穩定， 碳化硅不屬于有機硅化合物。Organosilicon compounds （有機硅化合物）are organometallic compounds containing carbon–silicon bonds. Organosilicon chemistry is the corresponding science of their preparation and properties. Most organosilicon compounds are similar to the ordinary organic compounds, being colourless, flammable, hydrophobic, and stable to air. Silicon carbide is an inorganic compound.
