The powder that is often sprinkled on molten metal can vary widely depending on the specific application and the desired outcome. Some common examples include dust, sand, or even fine metallic powders.
(what is the powder you sprinkle on molten metal)
In general, the purpose of sprinkling the powder on molten metal is to coat it in a protective layer that helps prevent oxidation and corrosion. This layer is typically made up of a material that is specifically designed to resist the elements involved in the metal’s processing, such as oxygen, carbon, and water.
One common type of powder used for this purpose is called a refractory material. Refractories are materials that have been specially formulated to withstand high temperatures and provide protection against corrosion. Examples of refractory materials include cast iron, stainless steel, and reactive glass. These materials are typically mixed together to form a paste or slurry, which is then applied to the molten metal.
Another common type of powder used for this purpose is called a non-conductive powder. Non-conductive powders do not allow electricity to flow through them, so they are less likely to conduct heat and are therefore less likely to cause problems during the metal’s processing. Examples of non-conductive powders include calcium sulfate, which is commonly used as a cladding material for blast furnaces.
It’s worth noting that there are many other types of powders that could be used for this purpose, each with its own unique properties and advantages. For example, some powders may be more effective at protecting against certain types of corrosion than others, while others may be better suited for different types of molten metal.

Overall, the choice of powder for sprinkling on molten metal will depend on a variety of factors, including the specific application, the intended protection level, and the materials available. It’s important to carefully consider these factors before making a decision, as the right powder can make all the difference in achieving the desired result.
