Physical & Chemical Properties

Silane belongs to highly flammable dangerous gas, easy to spontaneously ignite when contacting air, with strong chemical activity. It is slightly soluble in water, stable under dry and sealed storage conditions, and easy to react with oxidants, strong acids and other substances. In actual use and storage, it must be kept away from fire sources, high temperature and open fire, and stored in dry, cool and well ventilated dangerous goods warehouse to ensure transportation and use safety.
