Carbide is a chemical compound formed by the combination of carbon and a metallic or semimetallic element.
Carbides are used in a variety of industrial, technical, and home applications. Calcium carbide is a significant source of acetylene and other chemicals, but silicon, tungsten, and other element carbides are prized for their physical hardness, strength, and resistance to chemical assault, even at extremely high temperatures. Iron carbide (cementite) is a key component of steel and cast iron.
In the carbide structure, two carbon atoms are linked together by three covalent bonds. Pi-bonds make up two of the three covalent bonds. These pi-bonds are formed by the lateral overlapping of the p-orbitals. The sigma bond is formed when the s-orbitals collide head-on. Carbon hybridization is found in the carbide structure. Each carbon has a single pair attached to it.

Silicon Carbide
Silicon carbide (SiC) is a semiconductor base material composed of pure silicon and pure carbon. SiC can be doped with nitrogen or phosphorus to create an n-type semiconductor, or with beryllium, boron, aluminum, or gallium to create a p-type semiconductor. Despite the fact that silicon carbide comes in a variety of kinds and purities, semiconductor-grade silicon carbide has only lately been accessible to users in the industry.
Calcium Carbide
Calcium Carbide is a grayish-black lump or crystalline (sand-like) powder with a garlic-like odor. It is used to produce acetylene gas, as a reducing agent, and in steelmaking and metal cutting.
At roughly 2,200 °C (4,000 °F), it is manufactured industrially from calcium oxide (lime), CaO, and carbon in the form of coke.
Iron Carbide
Iron carbide is an iron-carbon intermetallic combination. It is made up of three Fe atoms and one C atom, and its chemical formula is Fe3C. Commercial iron carbide is composed of around 90% total iron and 6% to 6.5 percent total carbon. The product’s major application is as a metallic charge during steelmaking to replace hot metal, direct reduced iron, or steel scrap.

Frequently Asked Questions (FAQs)
1. Is sodium sulfate the same as salt?
Sodium sulfate is an inorganic chemical with the formula Na2SO4.
It is primarily used in the manufacture of detergents and the Kraft process of paper pulping. It can be found in all forms as white solids that are highly water-soluble. Decahydrate is a significant commodity chemical product, with an annual output of 6 million tonnes.
2. What is sulfur electronic configuration?
Sulfur electronic configuration is 1s2 2s2 2p6 3s2 3p4
3. What is CLF3 molecular geometry?
ClF3 has a T-shaped molecular geometry and trigonal bipyramidal electron geometry. This molecule has two lone pairs and three bound pairs, according to the ClF3 Lewis structure. ClF3 is a polar compound.
4. Why is flaring necessary?
Flaring is a method of disposing of flammable materials, mostly methane, as well as reducing odor irritants, health concerns, and negative environmental effects.
5. What is a volatile substance?
The term “volatile” refers to compounds with a high evaporation capability. They have fewer intermolecular interactions and, as a result, may be transferred to the vapor phase quickly. They also have higher vapor pressures and lower boiling temperatures.
6. What are ionic compounds?
Ionic compounds are formed by a process known as electron transfer, in which one atom transfers electrons to another. An atom of one element loses one or more electrons during electron transfer, and an atom of another element gains those electrons. Both atoms are involved in the electron transfer from ions.
7. What is convection in the atmosphere?
Convection in the atmosphere is frequently seen in our weather system. As the sun heats the Earth’s surface, the air above it warms and rises. If the conditions are favorable, this air can continue to rise, cooling and producing Cumulus clouds.
8. What is the process of distillation?
Distillation is the separation of a mixture of liquids based on variations in their boiling points (or volatility). Water may be extracted from a salt solution using this method.
9. What is the combustion process?
Combustion is a chemical process in which heat and light are produced. The most common sort of combustion is fire.
10. Is zinc a strong metal?
Zinc metal is a low-tensile-strength metal with less than half the tensile strength of mild carbon steel.
