Chromium (IV) oxide (CrO 2) is a magnetic compound. Its ideal shape anisotropy, which imparts high coercivity and remnant magnetization, made it a compound superior to γ-Fe 2 O 3. Chromium (IV) oxide is used to manufacture magnetic tape used in high-performance audio tape and standard audio cassettes.
Chromium (web browser) Chromium is a free and open-source web browser project, primarily developed and maintained by Google. [ 3] It is a widely-used codebase, providing the vast majority of code for Google Chrome and many other browsers, including Microsoft Edge, Samsung Internet, and Opera. The code is also used by several app frameworks .
Chromium compounds. Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist. [3] [4]
Hexavalent chromium. Hexavalent chromium ( chromium (VI), Cr (VI), chromium 6) is any chemical compound that contains the element in the +6 oxidation state (thus hexavalent ). [1] It has been identified as carcinogenic, which is of concern since approximately 136,000 tonnes (150,000 tons) of hexavalent chromium were produced in 1985. [2]
Chromium toxicity refers to any poisonous toxic effect in an organism or cell that results from exposure to specific forms of chromium —especially hexavalent chromium. [1] Hexavalent chromium and its compounds are toxic when inhaled or ingested. Trivalent chromium is a trace mineral that is essential to human nutrition.
Naturally occurring chromium ( 24 Cr) is composed of four stable isotopes; 50 Cr, 52 Cr, 53 Cr, and 54 Cr with 52 Cr being the most abundant (83.789% natural abundance ). 50 Cr is suspected of decaying by β + β + to 50 Ti with a half-life of (more than) 1.8×10 17 years. Twenty-two radioisotopes, all of which are entirely synthetic, have been ...
Chrome plating. Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome, or is said to have been chromed. The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, and increase surface hardness.
Chromium trioxide (also known as chromium (VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name. [6] This compound is a dark-purple solid under anhydrous conditions and bright orange when wet.
