Calcium carbide


Calcium carbide (carbonaceous calcium, calcium acetylenide) - CaC2 is a pure white crystalline substance. Compound of calcium with carbon.

Calcium carbide is produced by fusing carbonite and quicklime in electric furnaces. Molten calcium carbide releases from the furnace into special molds, where it hard. Harden calcium carbide crushes and sorts into of a certain size pieces.

Technical calcium carbide is a hard-crystalline substance. Calcium carbide is a dark gray or brown solid in appearance. Depending on the purity it gives a gray crystalline fracture with different shades. Calcium carbide greedily absorbs water., calcium carbide decomposes with a violent release of acetylene and a large amount of heat interacting with water, even cold. Decomposition of calcium carbide also occurs under the influence of atmospheric moisture.

Silicon carbide


Silicon carbide (carborundum) is a binary inorganic chemical compound of silicon with carbon.

The chemical formula is SiC. It occurs naturally in the form of an extremely rare mineral, moissanite. Silicon carbide powder was obtained in 1893. It is used as an abrasive, semiconductor, for imitating diamond inserts in jewelry.

Boron carbide


Boron carbide is a binary compound of boron with carbon, having the formula B4C (B12C3)., Black crystals in usual conditions. First obtained in 1893 by A. Moissant by reduction of boron oxide B2O3 with carbon at 2000 ° C.



Ferroalloys are alloys of iron with other elements (Cr, Si, Mn, Ti, etc.), used mainly for deoxidation and alloying of steel (for example, ferrochrome, ferrosilicon). Ferroalloys conventionally also include some alloys containing iron only as inclusions (silicocalcium, silicomanganese, etc.), and some metals and non-metals (Mn, Cr, Si) with a minimum content of inclusions.


They are obtained from ores or concentrates in electric furnaces or smelting mines (forges) and are used for deoxidation and alloying of iron-carbon alloys.


Iron dissolves the main element in smelting reduction, reduces its activity, lowers the melting point of the alloy.


When alloying and deoxidizing steel and alloys, the use of an alloying element in the form of a ferroalloy increases its absorption by the melt and reduces waste.


Ferroalloys are divided to the so-called "large" and "small" by the volume of production. Large ferroalloys are silicon, manganese, chromium. Small ferroalloys are ferro-tungsten, ferromolybdenum, ferrovanadium, alloys of alkaline-earth metals, ferroniobium, ferrotitanium and titanium-containing alloys, ferroboron, ferroboron and master alloys with boron, alloys with aluminum, alloys with rare earth metals, ferrosilicon, zirconium ferrosilicon, ferro aluminous zirconium, ferronickel and ferro cobalt.
