Compounds of chromium(IV) are slightly more common than those of chromium(V). The tetrahalides, CrF 4, CrCl 4, and CrBr 4, can be produced by treating the trihalides (CrX 3) with the corresponding halogen at elevated temperatures. Such compounds are susceptible to disproportionation reactions and are not stable in water.
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 most common form of lung malignancies in chromate workers is squamous cell carcinoma. [11] Ingestion of chromium(VI) through drinking water has been found to cause cancer in the oral cavity and small intestine. [11] It can also cause irritation or ulcers in the stomach and intestines, and toxicity in the liver.
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]
Trivalent chromium plating, also known as tri-chrome, Cr 3+, and chrome(III) plating, uses chromium sulfate or chromium chloride as the main ingredient. Trivalent chromium plating is an alternative to hexavalent chromium in certain applications and thicknesses (e.g. decorative plating). [2]
Chromite can be used as a refractory material because it has a high heat stability. [26] The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome, and stainless steel. Chromium is used as a pigment for glass, glazes, and paint, and as an oxidizing agent for tanning ...
