The carbide formula is \[C_{2}^{-2}\]. The Carbide formula represents that the carbide exists in a dianionic form state. On looking at the carbide ion formula you can not get an idea about the lone pairs and the hybridisation. For that, you need to have knowledge of the carbon electronic structure and its structure.

Surgical Tools - to operate properly and inefficiently, the medical industry needs more equipment and tools. These types of equipment are specified for certain procedures and situations. Surgical tools are used recurrently and should be able to live through procedures. Carbide metals are used in surgical tools and in many other tools related to medicine that save our lives. Surgical tools which are used nowadays are mostly composed of titanium or stainless steel. This makes a great example of grafted carbide and the way it merges makes useful tools. It is grafted to titanium or stainless steel to make vital tools used for surgeries.

Cemented Carbide - this is used for the creation of milling and drilling tools. Tools that are used for construction applications are made up of carbide metal compounds. This is where the market of this compound metal paves its way towards the construction applications and the formation of associated tools like drill bits, mining tips, etc. It is preferred more, over the use of stainless steel due to its resistance and hardness components.

Intermediate Transition Metal Carbide - This type of carbide is formed by the fusion of transition elements (having a similar size as that of carbon) and carbide ions.

You can avail all the well-researched and good quality chapters, sample papers, syllabus on various topics from the website of Vedantu and its mobile application available on the play store.

Ionic Carbide - Ionic carbides are formed by the combination of highly electropositive elements like alkali metals or alkaline earth metals and carbide ions. These ions are attracted to each other by the strong electrostatic force. This type of ionic carbide exhibits a high electronegativity difference. Examples of ionic carbides are calcium carbide.

Covalent Carbide - These types of carbide are formed by the fusion of carbide ions with elements with similar electronegativity. Boron and silicon have similar electronegativity as that of carbon. Therefore, these two elements form covalent carbide.

5. Why do you think Vedantu is reliable for downloading the study material of carbide - formula, structure, properties, preparations, and types?

Carbiding or carburizing is the process of producing carbide coating on a metal piece. This process is used in the metallurgy process.

Jewellery - as we can mould and reshape carbide to our likings it is also used in creating pieces of jewellery. We can combine it with other metals which makes carbide and jewellery a perfect match. This is the modern use of carbide metals in industries. The hardness which it holds makes it more attractive for jewellery makers. It is utilized in many ways, some are in crafting rings, hoops, necklaces, etc. If carbide is cut and polished in an efficient way we can create beautiful jewellery pieces

The carbide chemical formula is \[C_{2}^{-2}\]. It shows that carbide is a negative ion. It carries two negative charges. Therefore, it is called a diamniotic form of carbon. The carbide anion contains two carbon atoms. These atoms are bonded together with the three covalent bonds. From these three covalent bonds, one is sigma and the other two are pi-bonds. The pi-bonds are formed by the lateral overlapping and the sigma bond is formed by the head-on overlapping. The sigma bond is stronger than the pi bonds. The total or net bond strength of the carbide ion is high, due to the triple bond.

As you know there are a lot of metal compounds used for a definite reason and in disparate applications worldwide. A compound like a carbide stands on its own for not being only a durable metal but as well as recyclable.

Carbide contains a combination of elements such as carbon and tungsten. When the two of these elements are refurbished together they create an alloy that is resistant to rust, heat, scratches and pitting. It holds a very high density which makes carbide able to get compared with a diamond in terms of hardness.

Ionic Carbide - These types of carbides are also known as saline carbides. These are formed by the fusion of electropositive metals and carbide ions.

Carbide steel is a compound of carbon with another metallic alloy element. Generally known as tungsten carbide, which is a usual example of metal carbide. Potentially up to 70+HRC, carbide tools enable harder materials to be machined. It has a red hardness of about 10000C. It still has high hardness. Tungsten carbide is abrasion-resistant and extremely hard. Major uses of it are sports equipment, tips of a ballpoint pen, drill bits, etc. This is what is meant by carbide steel.

In carbide structure, two carbon atoms are attached to each other with the three covalent bonds. From these three covalent bonds, two bonds are pi-bonds. These pi-bonds are formed by the lateral overlapping of the p-orbitals. Another bond is the sigma bond, which is formed by the head-on overlapping of the s-orbitals. The hybridization exhibited by the carbon in the carbide structure is sp. Each carbon carries one lone pair on it.

Covalent Carbides - Covalent carbides are formed by the combination of low electropositive elements like silicon and boron. They exhibit low electronegativity differences. Some examples of covalent carbides are: Boron carbide and silicon carbide or commonly known as carborundum (SiC).

Carbides like carborundum (SiC), tungsten carbide are very hard in nature. These Carbides fall just under the diamond in terms of hardness.

Industrial Alloys - alloys that are specialized use carbide metal compounds the most and 17 % of them is mended with other metals. Carbide is variable and can be sharpened, combined and moulded with other metals to make useful compounds that can be utilized in electronics or other applications for commercial use. The popularly used combination of carbide is with copper, nickel, iron and silver to create different and new materials for distinguished purposes such as:

Mill Products - for mill products and mill inserts carbide is an efficient metal compound to be used. Over 10% of carbide is mostly used in mill products which are quite voguish. It’s manufactured in many different shapes and sizes. The type of metal carbide which comes in contact with it depends as well. This metal compound is quite variable because of the capabilities that it holds to be merged and its high density can be used to create precise applications for grading and milling.

Interstitial Carbide - Interstitial carbides are the carbides of the group-IV, -V, and VI transition metals of the periodic table. Interstitial carbides are formed so that the carbon atoms of the carbide ion get fit into the octahedral interstices of a close-packed metal lattice.

The carbides can be divided into various types, depending on the nature of the bond formed between the carbide ion and the metal or semi-metallic element.

Intermediate Transition Metal Carbide - Intermediate transition metal carbide is composed of transition metal and the carbide ion. The size of the transition metal and the carbide ion is similar in this type of carbide. Few examples of intermediate carbides are carbides of Iron like cementite Fe3C.

Carbide is the most common term used in inorganic chemistry and organic chemistry. Let’s come to the main question: what is carbide? The carbide is a chemical compound composed of carbon and metal or semi-metallic elements. It exists in an ionic form. The carbide group is attached to the metal or semi-metallic element with the ionic or covalent bond. The Carbide symbol is represented as \[C_{2}^{-2}\].  It represents that carbide ions are made up of two carbon atoms.

Interstitial Carbides - Interstitial carbides are composed of large transition metals and carbide molecules. The carbide ions occupy the interstitial sites of the closed packed metal lattice.
