Calcium - Wikipedia
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier homologues strontium and barium.It is the fifth most abundant element in Earth''s crust and the third most abundant metal, after iron and
The Importance of Metallurgical Slags and Their Evaluation
The Importance of Metallurgical Slags and Their Evaluation Ore is decomposed in smelting with heat and a chemical reducing agent such as calcium, driving off other elements as gases or slag and leaving the metal base behind. Blast Furnace Operation. In modern steel making, slags originate in a blast furnace from impurities in the iron ores
Flux (metallurgy) - Wikipedia
In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were carbonate of soda, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.

Jan 01, 1997· Calcium is less reactive than strontium or barium, forming a protective oxide-nitride coating in air that enables it to be machined in a lathe or handled by other standard metallurgical techniques. The chapter also illustrates the atomic and physical properties of alkaline earth metals.
Smelting - Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
Removal of impurities from metallurgical grade silicon
In this study, a novel metal assisted chemical leaching (MACL) was proposed to remove impurities from metallurgical grade silicon (MG-Si). HF acid leaching, one step MACL (1-MACL, HF + AgNO 3) and two step MACL (2-MACL, HF + AgNO 3 + H 2 O 2) were employed to purify MG-Si.The typical precipitates at Si grain boundaries before and after leaching were observed and analyzed by scanning electron
