[0002] Sodium metal is a silvery white active alkali metal with low melting and boiling points. It is widely used in industry and can be used to make sodium lamps, which are suitable for indoor and outdoor lighting. It reacts with water to produce sodium hydroxide and hydrogen. Sodium hydroxide is an important chemical raw material used in papermaking, synthetic rubber, dyes, etc. It synthesizes organic compounds such as alcohols and ethers, which are widely used in chemical, pharmaceutical, agricultural and other fields. It manufactures sodium-potassium alloys as thermal conductors for atomic reactors. It is used as a reducing agent to smelt metals such as potassium, zirconium, niobium, titanium, tantalum, etc. It is used to cast light metals such as aluminum and magnesium to form alloys to improve their strength and corrosion resistance. When preparing sodium metal, electrolysis is usually used. This method involves electrolyzing a molten mixture of sodium chloride and calcium chloride at high temperature. During the process, chlorine is produced at the anode, while sodium metal is precipitated at the cathode. The temperature is maintained at about 500°C. At this time, the sodium metal is in liquid state. Liquid sodium metal is not easy to store and has active chemical properties, so it needs to be cooled to a solid.
