by Harold C. Hodge (page images at HathiTrust) The occurrence and biological effects of fluorine compounds: annotated bibliography. 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. The flux used was premixed Borx(dec):fluorspar. The ratio of flux to mlcc's was The MLCC's were not crushed.

I have placed the MLCC's in a graphite crucible and brought the gas furnace to about C. At this point the flux was slowly added via a makeshift auger until all of the calculated amount was added.

Examples are fluorspar, calcium, fluoride * Alumina can act as a basic or acidic flux. Classes of Flux The degree of acidity or basicity of flux is often specified to characterize the slag chemistry for a particular system.

For example, steelmaking uses slags with more bases (lime and magnesia) than acids (silica and alumina). Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar.

Fluorspar is commonly used as a flux in aluminium melting, and significant quantities of fluoride dust may be released to the environment.

In certain cases barium chloride has been used as a flux for magnesium alloys; this is a significantly toxic substance and, consequently, considerable care is required in its use.

Founding and Casting The process of pouring molten metal into a cavity that has been molded according to a pattern of the desired shape.

When the metal solidifies, the result is a casting—a metal object conforming to that shape.
