Chromium(III) oxide (1308-38-9, 196696-68-1)
chromic oxide · chromium sesquioxide · dichromium trioxide
Chromium(III) oxide is the inorganic compound of the formula Cr 2O 3. It is one of the principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite.
Boric oxide (1303-86-2)
Boron trioxide (or diboron trioxide) is one of the oxides of boron. It is a white, glassy solid with the formula B2O3. It is almost always found as the vitreous (amorphous) form; however, it can be crystallized after extensive annealing (that is, under prolonged heat).
Dinitrogen trioxide (10544-73-7)
nitrogen trioxide · nitrous anhydride
Cobalt(III) oxide (1308-04-9)
Cobalt (III) oxide is the inorganic compound with the formula of Co2O3, most commonly used in bleach. Although only two oxides of cobalt are well characterized, CoO and Co3O4, procedures claiming to give Co2O3 have been described. Thus treatment of Co(II) salts such as cobalt(II) nitrate with an aqueous solution of sodium hypochlorite (also known as bleach) gives a black solid.
Bismuth(III) oxide (1304-76-3)
Bismuth(III) oxide is perhaps the most industrially important compound of bismuth. It is also a common starting point for bismuth chemistry. It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores.
Indium oxide (1312-43-2, 12672-71-8)
indium oxide (In2-O3)
Indium(III) oxide (In2O3) is a chemical compound, an amphoteric oxide of indium.
Thulium(III) oxide is a pale green solid compound, with the formula Tm2O3. It was first isolated in 1879 from an impure sample of erbia by Per Teodor Cleve, who named it thulia. It can be prepared in the laboratory by burning thulium metal in air, or by decomposition of their oxoacid salts, such as thulium nitrate.
Samaria (12060-58-1, 12651-06-8)
Samarium(III) oxide (Sm2O3) is a chemical compound.
Gadolinia (11129-31-0, 68609-39-2, 12064-62-9)
gadolinium oxide · digadolinium trioxide · gadolinium oxide (Gd2O3)
Gadolinium(III) oxide (archaically gadolinia) is an inorganic compound with the formula Gd2O3. It is one of the most commonly available forms of the rare-earth element gadolinium, derivatives of which are potential contrast agents for magnetic resonance imaging.
Rhodium(III) oxide (12036-35-0, 197082-00-1)
Rhodium(III) oxide (or Rhodium sesquioxide) is the inorganic compound with the formula Rh2O3. It is a gray solid that is insoluble in ordinary solvents.
Terbium oxide (12738-76-0, 12036-41-8, 162524-94-9)
Terbium(III) oxide, also known as terbium sesquioxide, is a sesquioxide of the rare earth metal terbium, having chemical formula Tb 2O 3. It is a p-type semiconductor when doped with calcium, and may be prepared by the reduction of Tb 4O 7 in hydrogen at 1300 °C for 24 hours. It is a p-type semiconductor.
Manganese(III) oxide (1317-34-6)
Manganese(III) oxide is a chemical compound with the formula Mn2O3.
Titanium(III) oxide (1344-54-3)
Titanium(III) oxide (Ti2O3) is a chemical compound of titanium and oxygen. It is prepared by reacting titanium dioxide with titanium metal at 1600 °C. Ti2O3 has the Al2O3, corundum structure.
