Metal sodium
Metallic sodium is a silvery-white, cubic-structured metal that is soft and lightweight enough to be easily cut with a small knife. It is less dense than water, with a density of 0.968 g/cm³, and has a melting point of 97.72°C and a boiling point of 883°C. When freshly cut, its surface exhibits a bright silver-white luster; however, upon exposure to air, it rapidly oxidizes, turning into a dull gray hue while maintaining good corrosion resistance. Sodium is an excellent conductor of both heat and electricity, and it also displays favorable magnetic properties. Moreover, the potassium-sodium alloy—when in liquid form—is widely used as a heat-transfer medium in nuclear reactors.
Metallic sodium is primarily employed in the production of sodium cyanide, indigo dyes, sodium methoxide, sodium peroxide, tetraethyl lead, and metallic titanium, among other applications in industries such as dyes, pesticides, and textile dyeing. Meanwhile, liquid chlorine finds extensive use across various industrial sectors, including pharmaceuticals, agriculture (pesticides), plastics, rubber, papermaking, textiles, and dye manufacturing. It is also indispensable for disinfecting municipal water supplies and treating wastewater.
