Encyclopedia > Dendrite (metal)

see dendrite for the biological usage (The term dendrite may also refer to the metallurgical dendrite. ... Main articles: Life All organisms (viruses not included) consist of cells, which in turn, are based on a common carbon-based biochemistry. ...


A dendrite in metallurgy is a characteristic tree-like structure of crystals growing as molten metal freezes, the shape produced by faster growth along energetically favourable crystallographic directions. Metallurgy is a domain of materials science and of materials engineering that studies the physical and chemical behavior of metallic elements and their mixtures, which are called alloys. ... Quartz crystal A crystal is a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating pattern extending in all three spatial dimensions. ... Crystallography (from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and graphein = write) is the experimental science of determining the arrangement of atoms in solids. ...


Dendrites also form during the freezing of many nonmetallic substances such as ice. ICE can refer to: InterCity Express, a German high-speed train Internal combustion engine, a fuel engine In-car entertainment In-circuit emulator, a computer hardware device In case of emergency, emergency number in mobile phones Institution of Civil Engineers, British civil engineer guild Immigrations and Customs Enforcement, U.S...

Flux (metallurgy) - Wikipedia, the free encyclopedia (433 words)
In metallurgy, flux is a substance which facilitates soldering, brazing, and welding by chemically cleaning the metals to be joined.
Common fluxes are: ammonium chloride or rosin for soldering tin; hydrochloric acid and zinc chloride for soldering galvanized iron (and other zinc surfaces); and borax for brazing, and welding ferrous metals.
In soldering of metals, flux serves a threefold purpose: it removes oxidation from the surfaces to be soldered, it seals out air thus preventing further oxidation, and by facilitating amalgamation improves wetting characteristics of the liquid solder.
