Other articles where Titanium carbide is discussed: titanium processing: Chemical compounds: Titanium carbide is used extensively for cutting tools because of its combination of wear resistance and high hardness. It is one of the hardest natural carbides. Titanium nitride has an attractive yellow colour that is used in jewelry and decorative glass coatings. The
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 oxide , CaO, and carbon in the form of coke at about 2,200 °C .
There are only two carbides that are considered completely covalent; they are formed with the two elements that are most similar to carbon in size and electronegativity, boron and silicon . Silicon carbide is known as carborundum and is prepared by
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C . It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°1,600° C .
In carbide: Ionic carbides The best characterized methanides are probably beryllium carbide and aluminum carbide . Beryllium oxide and carbon react at 2,000 °C to produce the brick red beryllium carbide, whereas pale yellow aluminum carbide is prepared from aluminum and carbon in a furnace.
