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.
