The role of metallic sodium

The uses of sodium are as follows: 1. As a reducing agent. It is used to reduce titanium, zirconium, niobium and tantalum from molten halides of important metals in national defense industry, and the domestic production level is very backward. 2. manufacturing chemical raw materials. It is used to produce sodium-containing compounds, such as cis-butadiene rubber, sodium hydride, sodium peroxide, sodium cyanide, sodium carbonate, etc. It is widely used, such as food, biology, pharmacy, rubber, leather, chemical industry, fire protection, ceramics, glass, water treatment and other industries. This is the largest part of sodium industrial application, and the domestic and international levels have their own advantages and disadvantages. 3. making alloys. An alloy of sodium and mercury, sodium amalgam, used as a reducing agent in organic synthesis. Sodium alloy is used to produce gasoline antiknock agent. Sodium alloy, used as coolant and heat exchanger in nuclear reactors. China's related technology level is low, except for some sodium amalgam, which basically depends on imports.
