FAQ

What is Pyrite (CAS: 1309-36-0)?

Pyrite, also known as fool's gold, is a chemical compound of iron disulfide with the chemical formula FeS₂ (CAS: 1309-36-0). It is a brassy yellow mineral with a metallic luster and is commonly found in sedimentary, metamorphic, and volcanic rocks.

What are the main uses of Pyrite (CAS: 1309-36-0)?

Pyrite is primarily used in the production of sulfur and sulfuric acid, as a sulfur source. It is also utilized as a source of iron in iron smelting. Additionally, it has applications in the production of fertilizers and as a pigment in paints due to its characteristic yellow color.

Is Pyrite (CAS: 1309-36-0) safe?

Pyrite is generally safe under normal conditions, but safety precautions should be taken. Exposure to metal sulfide dust can cause respiratory issues. It is advisable to wear protective equipment such as gloves and a dust mask when handling pyrite. Avoid inhaling dust and contact with the eyes. Proper ventilation is essential during handling.

How should Pyrite (CAS: 1309-36-0) be stored?

Pyrite should be stored in a dry, cool place away from direct sunlight and moisture. It should be kept in a tightly sealed container to prevent oxidation and the formation of sulfuric acid. Handling should be done with care to avoid dust formation and inhalation. It is recommended to store pyrite in a well-ventilated area and away from heat sources and flammable materials.
