The powder that people typically apply to hot metal is known as anodes, which are a type of material made up of a variety of metal ions bonded together in a specific arrangement. The primary purpose of applying anodes to hot metal is to reduce its electrical conductivity, which can make it more difficult for corrosion to occur.

There are several types of anodes that can be used to protect hot metal against corrosion. Some of the most common include zinc oxide, copper oxide, and magnesium oxide. These anodes work by creating a protective layer on the surface of the metal being protected, which helps to prevent the formation of rust and other forms of corrosion.
Zinc oxide, for example, is often used to protect iron and steel against corrosion. It works by forming a thin layer of oxides on the surface of the metal, which makes it less susceptible to attack by oxygen and water. Copper oxide, on the other hand, is commonly used to protect stainless steel from corrosion. It works by forming a protective film of copper oxide over the surface of the metal, which helps to prevent the formation of rust and other forms of corrosion.
Magnesium oxide, also known as magnesium hydroxide, is another type of anode that is commonly used to protect hot metal against corrosion. It works by forming a protective layer of magnesium hydroxide on the surface of the metal, which helps to prevent the formation of rust and other forms of corrosion.
In addition to these traditional anodes, there are also newer technologies available that are designed specifically to protect hot metal against corrosion. For example, some anodes contain silver or palladium particles, which have been shown to be effective at preventing corrosion. Others use special coatings or treatments that are applied to the metal being protected.

Overall, the use of anodes to protect hot metal against corrosion is an important practice in industries such as construction, transportation, and manufacturing. By using anodes, companies can ensure that their products remain durable and resistant to damage, even when exposed to harsh environmental conditions.
