In carbide: Ionic carbides important of these compounds is calcium carbide, CaC 2. The primary use for calcium carbide is as a source of acetylene for use in the chemical industry. Calcium carbide is synthesized industrially from calcium
Zirconium carbide is a chemical compound of zirconium metal and carbon with the formula ZrC. It is an introduction phase with a wide region of homogeneity, which ranges from to 50 at. % carbon, which corresponds to the formula ZrC and ZrC, respectively [1].
Silicon carbide (SiC), also known as carborundum / k r b r n d m /, is a semiconductor containing silicon and occurs in nature as the extremely rare mineral SiC powder has been massproduced since 1893 for use as an of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications
Boron carbide, (B4C), crystalline compound of boron and carbon. It is an extremely hard, synthetically produced material that is used in abrasive and wearresistant products, in lightweight composite

It is used as a deoxidizer in the refining of iron, steel, copper, and copper alloys. It is a constituent of several lead and aluminum alloys. It is also used in extracting certain metals from their ores. Limestone, marble, chalk, Iceland spar, coral, pearls, and eggshells are all made up mainly of calcium carbonate.
Silicon carbide is a covalent solid made up of carbon and silicon. It is of great hardness with a value of to 10 on the Mohs scale, and its chemical formula is SiC, which may suggest that carbon is linked to silicon by a covalent triple bond, with a positive charge (+
Tungsten is a transition metal known for its outstanding properties, especially when combined with other elements in compounds such as tungsten carbide. The name Tungsten was derived from the Nordic words tungquot; and quot;sten, which combined mean heavy stone [3]. Tungsten is also known as wolfram, from which it takes its chemical symbol
List of Chemical Compounds, Their Common Names and Formulas Chemical Compound. A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. There will be a fixed ratio for a chemical compound determining the composition of it.
Carbide, any of a class of chemical compounds in which carbon is combined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical
Materions 50+ years of inorganic chemical manufacturing experience allows us to deal successfully with issues that arise when working with carbide compounds. Carbides can be brittle and reactive to moisture and oxygen and can experience chemical reactions that potentially release methane or
It is also known as calcium acetylide, phenyl glyceryl ether diacetate, and glycerol phenyl ether diacetate. Calcium Carbide in its pure form appears as a colourless crystalline solid and is a rocklike structure at room temperature.
Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important
Carbide In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by chemical bonding type as follows: (i) saltlike, (ii) covalent compounds, (iii) interstitial compounds, and (iv) `intermediate` transition metal carbides.
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600#176; C (4,700#176; F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400#176;1,600#176; C (2,550#176;2,900#176; F). For fabrication, a process developed in the 1920s is employed: the powdered tungsten carbide
