Chromium word list, defined
- CHROMIUM /ˈkroʊmiəm/ · noun
- A hard, lustrous, steel-gray metallic element (symbol Cr, atomic number 23) used chiefly in stainless steel and electroplating, and essential as a trace element in human metabolism.
- CHROME /krəʊm/ · noun
- Chromium metal, especially when used as a bright, mirror-like protective plating on other metals; also, by extension, any shiny metallic trim or finish on vehicles and appliances. Related: chromium, plating, finish, trim.
- DICHROMATE /daɪˈkroʊmeɪt/ · noun
- A salt or ester of dichromic acid containing the divalent anion Cr₂O₇²⁻, typically orange-red and strongly oxidizing; the best-known example is potassium dichromate. Related: bichromate.
- CHROMITE /ˈkroʊmaɪt/ · noun
- A black or brownish-black crystalline mineral, iron chromium oxide (FeCr₂O₄), that is the principal commercial source of the metal chromium and of chromium compounds. Related: chromic iron ore, chrome ironstone, chrome ore.
- ELECTROPLATING /ɪˌlɛktrəˈpleɪtɪŋ/ · noun
- The process of depositing a thin layer of metal, such as gold, silver, chromium or nickel, onto the surface of another object by means of an electric current passed through an electrolyte solution. Related: metal plating, electrodeposition, galvanoplasty.
- PASSIVATION /pæsɪˈveɪʃən/ · noun
- The process of making a metal surface resistant to corrosion by forming a thin layer of oxide on its surface, or the state of being in this condition. In psychology, the process of suppressing or hiding one's true feelings or intentions. Related: corrosion protection, oxide layer, surface treatment, metal coating.
- CORROSION /kəˈroʊʒən/ · noun
- The gradual destruction or wearing away of a material, especially a metal, by chemical reaction with its environment, most commonly through oxidation such as rusting. Related: erosion, rust, oxidation, decay.
- STAINLESS /ˈsteɪnliːs/ · adjective
- Not containing or liable to rust; resistant to corrosion. Resistant to corrosion or decay. Related: rustless, corrosion-resistant, non-rusting, inert.
- ALLOY /ˈælɔɪ/ · noun
- A metal made by combining two or more metallic elements, or a metal and a nonmetal, to give greater strength or resistance to corrosion. As a verb, to alloy means to mix or blend metals in this way. Related: mixture, blend, compound, fusion.
- METAL /ˈmɛtəl/ · noun, verb
- A naturally occurring inorganic solid substance with a characteristic high density and a crystalline structure, composed of atoms of a metal element, such as iron, copper, or gold. To cover or coat with a thin layer of metal. Related: metallic, metallically, metallurgy, mineral.
- OXIDATION /ˌɒksɪˈdeɪʃən/ · noun
- The process of losing electrons, resulting in the gain of oxygen or the loss of hydrogen, often accompanied by a change in color or the release of heat. Related: corrosion, rusting, decomposition, combustion.
- REDUCTION /riːdʌkʃən/ · noun, verb
- The act of making something smaller or less in amount, degree, or extent. A decrease in size, amount, or degree. Related: diminution, lessening, reduction, diminishment.
