            Application field
            1, used as a dehydrating agent, because it can strongly absorb water;
            2, in the manufacture of electronic tubes, it is also used to absorb oxygen and water vapor remaining in the real tube;
            3, the preparation of sodium potassium alloy, melting point is very low, at room temperature is liquid, can be used to replace mercury to manufacture thermometers, used for heat exchange carrier;
            4, preparation of tetraethyl lead, used in pharmaceutical, rubber industrial grade in organic synthesis for reduction and photocell production.

              Next: Liquid Sodium methoxide
              Prev: Potassium superoxide
