Silicon Carbide (SiC), an extremely hard and highly abrasion-resistant synthetic crystalline compound made up of silicon and carbon, boasts an Mohs hardness rating of 9 and has long been utilized to produce products such as sandpaper, grinding wheels, cutting tools and refractory materials for furnaces brick kilns since the 19th century. More recently however, SiC has also become widely utilized for the production of ceramic insulators and semiconducting light emitting diode substrates.

SiC’s corrosion resistance stems largely from its surface coating of oxide oxide layers that form on its surface, providing protection from water and oxygen attack while withstanding penetration from acids, bases and aggressive chemicals such as nitric acid. In some instances, these layers even protect against oxidizing substances like nitric acid which might otherwise attack.

Pressureless sintered silicon carbide has proven itself highly corrosion-resistant in various applications, outshone by materials like cast steel, inert alumina and high-grade nickel alloys in terms of chemical and thermal stability. Furthermore, pressureless sintered silicon carbide’s resistance to abrasion and erosion makes it far superior compared to most metals such as alumina (3 times that of steel) as well as its great wear resistance against wear-and-tear corrosion compared to refractory cast steel (3 times that of steel).

Silicon carbide and silicon nitride’s corrosion behavior varies significantly with environmental conditions, yet corrosion models for both materials have made significant progress in accurately depicting them. Corrosion mechanisms involving complex environments depend on chemical species present, their reaction sequences, surface changes to microstructure morphologies as well as changes in surface and microstructural morphologies of materials that interact together to cause corrosion to take place.

Silicon carbide tubes boast long service lives and are particularly ideal for conveying abrasive, corrosive or toxic chemicals. Their durability means they can withstand temperatures above 120 oF (48oC), high pressures and mechanical stresses. As an alternative to steel tubing they’re used in power plants, metallurgy and the chemistry industry – as well as equipment used to handle powders from coal gasification processes (gasification/cracking/blast furnace/cement kiln), blocks/ash from coal gasification/crack/blast furnace/cement kiln/cement kiln/cement kilns/cement kilns/cement kilns/cement kilns/cement kilns.

Silicon carbide’s crystal form features covalent bonds between silicon and carbon atoms that form two primary coordination tetrahedra with four silicon and four carbon atoms connected at each corner, creating an extremely hard material with a Mohs hardness rating of 9, approaching that of diamond. Silicon carbide can be found everywhere from sandpaper and cutting/grinding wheels to furnace linings for furnaces and rocket engines; additionally it exhibits fascinating electrical properties.

Reaction bonding and sintering are two methods used to produce silicon carbide, each producing different effects on its microstructure. Reaction bonded silicon carbide can be produced by infiltrating mixtures of SiC and carbon with liquid silicon that reacts into more SiC; sintered silicon carbide can be made using non-oxide sintering aids to form pure SiC powder powder into compacts for reaction bonding; this method does not produce as dense of an end product as reaction bonded SiC does.
