What Is Magnesium Powder?

Magnesium powder usually refers to the powder state of elemental magnesium. It is a silvery white powder with metallic luster. It is an active metal and flammable when wet. It produces strong white light and high heat when burning. It reacts with water or moisture to release hydrogen, releases a lot of heat, and causes combustion or explosion. It reacts violently with chlorine, bromine, iodine, sulfur, phosphorus, arsenic and oxidants, and is dangerous to combustion and explosion.
Magnesium powder is mainly used as a reducing agent, making flash powder, lead alloy, and desulfurizing agent in metallurgy (when used as a desulfurizing agent raw material in the metallurgical industry, the magnesium powder particles are coated with a layer of passivating agent to prevent the magnesium powder from oxidizing). In addition, it is used in organic synthesis, lighting agents, etc. It is mainly prepared by electrolytic molten magnesium chloride and electrolytic molten dehydrated carnallite.
