(Ferrous Sulphide or Iron Sulphide) supplier Distributor Manufacturer in chennai Taminadu india

Iron (II) sulfide (Ferrous Sulphide or Iron Sulphide) is a chemical compound with the formula FeS. In practice, iron sulfides are often non-stoichiometric. Powdered iron sulfide is pyrophoric.

FeS, Ferrous Sulphide or Iron Sulfide can be obtained by reacting iron and sulfur.

S8 (s) + 8Fe(s) → 8FeS(s)

We can offer Ferrous Sulphide or Iron Sulfide in the form Sticks, Lumps and Powder.

"Ferrous Sulphide or Iron Sulfide" exists in several distinct forms which differ in the stoichiometry and properties:

Pyrrhotite, Fe1-xS, a mineral as well as the waste product of the Desulfovibrio bacteria, pyrrhotite displays ferrimagnetism.

Troilite, FeS, which has similar material to pyrrhotite, but does not possess ferromagnetic properties.

Mackinawite, Fe1+xS, the least stable from of iron sulfide, mackinawite has a layered structure.

Pyrite, mineral form of FeS2 with a gold-like appearance, making it also known as "fool's gold.". it is largely Ferrous Sulphide or Iron Sulfide.

Pedagogical uses 

Certain chemical principles are nicely illustrated using the chemistry of Ferrous Sulphide or Iron Sulfide. The methods of chemical composition can be shown by the production of iron (II) sulfide from iron and sulfur.

This reaction is exothermic as more energy is given out than taken in.

Iron shows ferromagnetism; iron sulfides do not.

Biological and biochemical uses

The presence of Ferrous Sulphide or Iron Sulfide as a visible black precipitate in the growth medium peptone iron agar can be used to distinguish between microorganisms that produce the cysteine metabolizing enzyme cysteine desulfhydrase and those that do not. Peptone iron agar contains the amino acid cysteine and a chemical indicator, ferric citrate. The catalysis of cysteine releases hydrogen sulfide gas that reacts with the ferric citrate to produce Ferrous Sulphide or Iron Sulfide.

Uses
Ferrous Sulphide or Iron Sulfide sticks are widely used as a laboratory chemical for the preparation of Hydrogen Sulphide gas, by famous KIPP'S apparatus when comes in contact with dilute mineral acids.

In foundries, during electric melting, residual sulphur level decreases due to cleaner melting practices and the use of low sulphur steel scrap. Ferrous Sulfide or Iron Sulphide is found that iron does not readily respond to inoculants if Sulphur is below 0.04%. Then it is necessary to resulphurize by using Ferrous Sulphide.

In Alloy And Stainless Steel Industries To Control Hydrogen Embrittlement It is very convenient and economic to use Ferrous Sulphide or Iron Sulfide for resulphurization in these steels to hold the right level of 'S' and ensuring not to drop 'S' level.

Ferrous Sulphide or Iron Sulfide is used as a resulphurizing agent in the production of carbon, alloy and stainless types of free cutting steels. Ferrous Sulphide or Iron Sulfide acts as an alloying agent to improve machineability of steel castings which are used to manufacture various steel components.

Sulphur in form of Ferrous Sulphide or Iron Sulfide is added along with FeSi & FeMn to increase the 'S' contents of electrically melted iron. Addition of FeS Ferrous Sulphide or Iron Sulfide influences white iron formation and obtain 'S' contents approximately 0.15%

The Purification Of Crude Phosphoric Acid Ferrous Sulfide is used in cake form as a reducing agent to remove heavy metal impurities from phosphoric acid.

Elemental Sulphur has very low melting point and its tendency to float on the surface of molten metal resulting in the release of Sulphur dioxide, an undesirable gas which pollutes the working environment. Moreover, low melting eutectic brittle compounds form along the grain boundaries and mechanical properties are deteriorated. Hence Ferrous Sulphide or Iron Sulfide and not Sulphur is used for increasing sulphur content of Iron and Steel.
