In recent years, silicon carbide bricks and shapes are widely used in various industries under the name of ceramic coatings. Due to having some special and unique characteristics, silicon carbide has excellent coating power, and for this reason, it is used as one of the best coating options in the industry. Among the most important features and special and unique characteristics of silicon carbide, the following can be mentioned: Black Silicon Carbide (Black Silicon Carbide) is a non-oxidizing ceramic material that is referred to by other trade names such as black silicon carbide, carborundum and sanding powder. Black silicon carbide with different characteristics such as 9.15 Mohs hardness - stability against acidification and heat - resistance to high heat and thermal shock is a widely used material in various industries, among its consumables in the abrasive industry can be made Abrasive parts with resin bands - acid washing machines - sanding stones - cutting tools mentioned. Due to the excellent coating power of silicon carbide, currently various industries use various methods and also use the most advanced and latest technology to create coating on various materials such as metals and glass. This work increases the hardness, strength and resistance of metals and glass significantly. 
With the progress of science and conducting extensive research on silicon carbide, specialists and experts have succeeded in combining it with other materials and producing a combination with more favorable properties. Compounds including silicon carbide are widely used in the industry due to having more favorable properties, and day by day we see an increase in their applications in the industry. Nickel and Silicon Carbide composite coating is one of the most widely used and best types of composite coatings in the world, which is widely used due to its unique and very desirable properties. Nickel and silicon carbide composite coating is considered as one of the most widely used industrial coatings, the best alternative to chrome coating. The reason for this is the cheapness of ceramic powder as well as the high resistance of this coating against wear. This coating is used in various industries to protect commercial parts against friction, and this coating is widely used in industrial valve production industries. In pipe transmission lines, because the contents of pipelines cause corrosion and wear in pipes, nickel and silicon carbide composite coating is used as a protective coating. The nickel and silicon carbide coating used in pipe transmission lines is very resistant to corrosion and friction, and for this reason, this composite coating is used in pipe transmission line construction industries. 
The anti-corrosion and anti-friction properties of this coating have made coatings such as tungsten carbide coating and chrome coating no longer used in pipeline production industries.
- what is the structure of silicon carbide
Silicon carbide, denoted by the chemical formula SiC, is a solid crystalline mineral. This compound is used in industry as a semiconductor and ceramic, which is usually called carborundum. Silicon carbide occurs naturally in a very rare mineral called moissanite. Pure silicon carbides appear as colorless and transparent crystals. When impurities such as nitrogen are added to them, silicon carbide crystals appear green or blue to the surface of the impurity. Silicon carbide is mostly used for its high hardness and strength, although its combined ceramic and semiconducting properties make it an excellent choice for making fast-response, high-voltage, and high-temperature devices. For more information in this regard, follow us in the article in Jahan Chemi Physik magazine. Silicon carbide, also known as Carborundum, is a combination of silicon and carbon. Silicon carbide is a semiconductor material that is used as an emerging material for making semiconductor devices. This compound was discovered by Edward Acheson in 1891 and is actually one of the most important industrial ceramic materials discovered and played a major role in the industrial revolution and is still widely used as an additive for abrasive materials and the production of steel and structural ceramics. is used

Silicon carbide or silicon carbide or carborundum with the chemical formula Sic is a rare mineral in nature. This substance is a crystalline solid and its pure samples are usually colorless and transparent. If some impurities such as aluminum or nitrogen are added to silicon carbide, its color will turn green or blue depending on the amount of added impurities. This material is made of a combination of silicon and carbon, and due to its properties such as high mechanical resistance, semi-conductor, and also being ceramic, it is used in many industries, especially the industries of high voltage and fast response devices. 
Today, this material is used as an additive in the production of steel, ceramics and abrasive materials. Currently, in order to use this substance in different industries, its production is done in three ways, which are: Nitride Bonded Silicon Carbide (NBSC) Porous Silicon Carbide (SSC) Reactive Silicon Carbide (RBSC) Of course, the production of this material is done in different forms, such as clay bonded carbide and deposited silicon carbide, which are less useful. In the following, we will talk about the production methods as well as the applications of this material. Community Verified icon As mentioned, silicon carbide is a very rare and rare mineral, and due to its widespread use, today its production is done artificially and by synthesis. Since 1893, its powder has been mass-produced completely artificially and is used to make abrasive materials. The synthetic method or the Acheson method is known as the artificial method of silicon carbide production, and in this method, pure silicon is first combined with ground petroleum coke or quartz sand (carbon) in an electric resistance furnace, and then it must be heated to a temperature of 2500 degrees Celsius. This material is usually produced in the form of a fine powder and is black or green in color, of course, its color will largely depend on the quality of the raw materials. 
In general, silicon carbide is used in the production of many refractory products and abrasive materials, and now we intend to examine the uses and uses of this material in industries in a more detailed manner. In general, the uses and uses of this material are as follows: an be used to produce hard ceramics, especially ceramic plates for bulletproof vests Can be used to produce all kinds of cutting and abrasive tools Can be used to make acid washing machines Can be used to produce plants for smelting industries Can be used to produce telescope mirrors Can be used in steel industries Can be used in the jewelry industry Can be used in the production of graphene Can be used in nuclear industries Can be used to print carborundum Can be used in quantum physics Community Verified icon
