  2. Chromic acid - Wikipedia

    en.wikipedia.org/wiki/Chromic_acid

    Chromic acid is capable of oxidizing many kinds of organic compounds and many variations on this reagent have been developed: Chromic acid in aqueous sulfuric acid and acetone is known as the Jones reagent, which will oxidize primary and secondary alcohols to carboxylic acids and ketones respectively, while rarely affecting unsaturated bonds. [12]

  3. Chromate conversion coating - Wikipedia

    en.wikipedia.org/wiki/Chromate_conversion_coating

    For aluminum, the chromate conversion bath can be simply a solution of chromic acid. The process is rapid (1–5 min), requires a single ambient temperature process tank and associated rinse, and is relatively trouble free. [2] As of 1995, Henkel's Alodine 1200s commercial formula for aluminum consisted of 50-60% chromic anhydride CrO

  4. Chromic acid cell - Wikipedia

    en.wikipedia.org/wiki/Chromic_acid_cell

    The chromic acid cell is a type of primary cell which uses chromic acid as a depolarizer. The chromic acid is usually made by acidifying (with sulfuric acid) a solution of potassium dichromate. The old name for potassium dichromate is potassium bichromate and the cell is often called a bichromate cell. [1]

  5. Chrome plating - Wikipedia

    en.wikipedia.org/wiki/Chrome_plating

    Hexavalent chromium plating, also known as hex-chrome, Cr 6+, and chrome(VI) plating, uses chromium trioxide (CrO 3, also known as chromic anhydride) as the main ingredient. Hexavalent chromium plating solution is used for both decorative and hard plating, as well as bright dipping of copper alloys, chromic acid anodizing , and chromate ...

  6. Anodizing - Wikipedia

    en.wikipedia.org/wiki/Anodizing

    Chromic acid produces thinner, 0.5 μm to 18 μm (0.00002" to 0.0007") [16] more opaque films that are softer, ductile, and to a degree self-healing. They are harder to dye and may be applied as a pretreatment before painting. The method of film formation is different from using sulfuric acid in that the voltage is ramped up through the process ...

  7. Chromium trioxide - Wikipedia

    en.wikipedia.org/wiki/Chromium_trioxide

    Chromium trioxide (also known as chromium(VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO 3. 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. The substance dissolves in water ...

  8. Suture materials comparison chart - Wikipedia

    en.wikipedia.org/wiki/Suture_materials...

    Chromic is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines. Due to undergoing a ribbon stage chromicisation (treatment with chromic acid salts), the chromic offers roughly twice the stitch-holding time of plain catgut. Chromic is absorbed by enzymatic degradation.

  9. Potassium chromate - Wikipedia

    en.wikipedia.org/wiki/Potassium_chromate

    Unlike the less expensive sodium salt, potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required. [1] It is as an oxidizing agent in organic synthesis.
