Vanadium(IV) dioxide is an inorganic compound with the formula VO2. It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO]2+ and in alkali to give the brown [V4O9]2− ion, or at high pH [VO4]4−.
TELLURIUM DIOXIDE (59863-17-1, 7446-07-3, 14832-87-2)
Tellurium dioxide (TeO2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO2, and the synthetic, colourless tetragonal (paratellurite), α-TeO2. Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO2.
GERMANIUM DIOXIDE (1310-53-8)
Germanium dioxide, also called germanium oxide and germania, is an inorganic compound with the chemical formula GeO2. It is the main commercial source of germanium. It also forms as a passivation layer on pure germanium in contact with atmospheric oxygen.
ZINC SULFIDE (12138-06-6, 12169-28-7, 1314-98-3)
Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.
iron oxide · ferric oxide · red iron oxide
Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is the oldest known Fe oxide mineral and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.
hydrogen sulfide (7783-06-4, 7704-34-9, 37331-50-3)
Hydrogen sulfide is the chemical compound with the formula H 2S. It is a colorless gas with the characteristic foul odor of rotten eggs. It is very poisonous, corrosive, and flammable.
Nickel sulfide (1314-04-1, 12035-72-2, 11113-75-0, 16812-54-7)
millerite · nickel sulphide · nickel sulfide (2:1)
Nickel sulfide is the inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide. Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.
VANADIUM PENTOXIDE (1314-62-1)
Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent.
Ceric oxide (1306-38-3)
cerium oxide · cerium dioxide · ceric oxide (CeO)
Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores.
CARBONYL SULFIDE (463-58-1)
Carbonyl sulfide is the organic compound with the linear formula OCS. Normally written as COS, it is a colourless flammable gas with an unpleasant odor. It is a linear molecule consisting of a carbonyl group double bonded to a sulfur atom.
