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.
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.
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.
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.
FERROUS OXIDE (17125-56-3, 1345-25-1)
Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron(III) oxide (ferric oxide).
Molybdenite (1317-33-5, 1309-56-4)
molybdenum disulfide · molybdenum sulfide · Mo3S4
Molybdenum disulfide is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS 2. The compound is classified as a transition metal dichalcogenide.
Zinc silicate (13597-65-4, 68611-47-2)
Phosphine (7803-51-2, 51457-48-8, 12185-10-3, 7723-14-0)
phosphane · hydrogen phosphorus, PH3
Phosphine (IUPAC name: phosphane) is the compound with the chemical formula PH3. It is a colorless, flammable, toxic gas and pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4).
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.
SELENIUM DIOXIDE (12640-89-0, 7446-08-4)
selenium oxide · selenium trioxide · Selenium Oxides
Selenium dioxide is the chemical compound with the formula SeO2. This colorless solid is one of the most frequently encountered compounds of selenium.
MANGANESE CARBONATE (598-62-9, 17375-37-0)
Manganese carbonate is a compound with the chemical formula MnCO3. Manganese carbonate occurs naturally as the mineral rhodochrosite but it is typically produced industrially. It is a pale pink, water-insoluble solid.
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.
Oldhamite (12015-71-3, 20548-54-3, 1344-81-6)
In horticulture, lime sulfur (British spelling lime sulphur) is a mixture of calcium polysulfides formed by reacting calcium hydroxide with sulfur, used in pest control. It can be prepared by boiling calcium hydroxide and sulfur together with a small amount of surfactant. It is normally used as an aqueous solution, which is reddish-yellow in colour and has a distinctive offensive odour.
Tin dioxide (18282-10-5, 1317-45-9)
tin oxide · stannic oxide
Tin dioxide (tin(IV) oxide), also known as stannic oxide, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry.
Cyclooctasulfur (1326-66-5, 10544-50-0)
Octasulfur is an inorganic chemical with the chemical formula S 8. It is a yellow solid, and is odourless and tasteless. It is the most common allotrope of sulfur.
Pentacene is a polycyclic aromatic hydrocarbon consisting of five linearly-fused benzene rings. This highly conjugated compound is an organic semiconductor. The compound generates excitons upon absorption of ultra-violet (UV) or visible light; this makes it very sensitive to oxidation.
