A catalogue of pigments printed around 1840 lists a green oxide of chromium, which is believed to be chromium oxide. Also, in 1969 Kühn, using microscopy and emission spectroscopy, found chromium oxide in three paintings which dated between 1845 and 1850. It is widely accepted that chromium oxide was used before the hydrated version.
When chromium oxide is reduced into molten iron, practically we have three choices of reductant, namely carbon, silicon and aluminum. In this paper the reduction of chromium oxide stainless steel slags was shown to be technically feasible by reviewing fundamental knowledges for smelting...
Silver Oxide is an odourless, fine black or dark brown cubic crystals. The chemical formula is Ag 2 O. When the aqueous solutions of silver nitrate and alkali hydroxide reacts together, Silver Oxide is produced. Its IUPAC name is Silver(I) oxide and density is 7.14 g/cm 3. It is soluble in acid, alkali and insoluble in ethanol.

  • All the latest news about chromium oxide from Phys.org. Researchers have found that a solid oxide protective coating for metals can, when applied in sufficiently thin layers, deform as if it were a liquid, filling any cracks and gaps as they form.
  • Chromium (IV) oxide (CrO 2) is used to manufacture magnetic tape, where its higher coercivity than iron oxide tapes gives better performance. In well drilling muds as an anti-corrosive. In medicine, as a dietary supplement or slimming aid, usually as chromium (III) chloride or chromium (III) picolinate.

To study an atomic structure one applies an atom wavelength radiating. By means of X-Ray crystallography one studies metals, alloys, minerals, inorganic and organic compounds, polymers, amorphous materials, liquids and gases, protein molecules, nucleic acids etc.

Chromium(VI) oxide is used for chromium plating; copper stripping; as an oxidizing agent for conversion of secondary alcohols into ketones (Jones oxidation); as a corrosion inhibitor; in purification of oil; and in 'chromic mixtures' for cleaning laboratory glassware. 1. It is used for electroplating and...
