What is the mass of silicon made? Silicon tetrachloride vapors react with moisture in air to produce dense white clouds of silica and hydrogen chloride. Phosphorus-doped aluminium oxide thin films were deposited in a flow-type ALE reactor from AlCl3, H2O and from either P2O5 or trimethyl-phosphate. Therefore, this product should be confined within enclosed equipment and should not be vented in to air. stream So it fulfills the octet rule and the silicon atom is stable. Readily undergoes violent chemical changes at elevated temperatures and pressures. To balance SiCl4 + H2O = SiO2 + HC. By Staff Writer Last Updated March 31, 2020.
