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).
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.
CADMIUM CARBONATE (513-78-0, 93820-02-1)
Otavite is a rare cadmium carbonate mineral with the formula CdCO3. Otavite crystallizes in the trigonal system and forms encrustations and small scalenohedral crystals that have a pearly to adamantine luster. The color is white to reddish to yellow brown.
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.
SELENIUM DIOXIDE (12640-89-0, 7446-08-4)

Selenium dioxide is the chemical compound with the formula SeO2. This colorless solid is one of the most frequently encountered compounds of selenium.
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.
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 Phosphate (13847-22-8, 7779-90-0)
Zinc phosphate (Zn3(PO4)2) is an inorganic chemical compound used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment.
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.
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.
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.
CADMIUM SULFIDE (68859-25-6, 1306-23-6)
Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium.
CUPRIC OXIDE (1317-38-0)
copper dioxide (CuO2) · copper oxide (CuO)
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or cuprous oxide. As a mineral, it is known as tenorite.
Zinc silicate (13597-65-4, 68611-47-2)
Phosphorus pentasulfide (1314-80-3)
Phosphorus pentasulfide is the inorganic compound with the formula P2S5 or dimer P4S10. This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities.
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.
