Silicon carbide (SiC) is a ceramic material that has found applications in a wide range of fields. It offers high-temperature strength, good wear resistance, small thermal expansion coefficient and chemical corrosion resistance.
This type of refractory ceramic has many applications in the chemical industry, process engineering and energy production. SiC also finds use in the ballistic armour field, where it is used to reliably stop projectiles.
Ceramic zirconia is a material used in a variety of applications. Its hardness and chemical inertness make it the ideal material for valves, which require excellent wear, temperature, and thermal shock resistance.
Silicon carbide, or SiC, is a semiconductor that occurs naturally as the mineral moissanite, and has been mass-produced since 1893 for use in industrial abrasives and high-performance ceramics. It is also used in automotive applications, including brake discs.
Various stabilizing agents (yttria, ceria, magnesia, and alumina) are added to zirconia to change its properties and characteristics. Some of these additives are designed to toughen and stabilize zirconia, making it more ductile.
Yttria-stabilized zirconia (YTZP) is a common grade of zirconia that has excellent mechanical properties. It can be manufactured in a wide range of aesthetic appealing colors and polished to a high luster.
Refractory materials are used in a variety of applications. They are durable and resistant to extreme temperatures, making them a great choice for furnaces and kilns that require high heat output.
Refractories can be made from several different materials. Some are ceramics and have excellent combinations of chemical inertness, high melting points and low thermal expansion. Others are non-ceramic, but still have strong strength.
Silicon carbide is a type of refractory material that is often used for its excellent thermal and mechanical stability. It is composed of a silicon atom surrounded by six oxygen atoms.
Silicon carbide can withstand extreme temperature changes, making it ideal for use in flame tubes and burner nozzles. It can also withstand oxidation and corrosion, making it a great choice for use in a range of applications.
silicon carbide ceramic
Silicon carbide ceramic is a highly hard covalently bonded material that occurs naturally in minerals. It is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice.
This enables the crystalline material to have very high thermal conductivity and low coefficient of thermal expansion as well as being resistant to acid corrosion and oxidation. This unique combination of physical and chemical properties makes silicon carbide an ideal material for a variety of applications including wide bandgap semiconductors in the electronics industry, structural ceramics for automotive and aerospace applications and as an abrasive.
SiC has been used since the late 19th century as an abrasive for grinding wheels and cutting tools. Today, it is also utilized in refractory linings for industrial furnaces, wear-resistant parts for pumps and rocket engines, and as semiconducting substrates for light-emitting diodes.
aluminum nitride ceramic
Aluminum nitride (AlN) is an extremely useful technical ceramic because of its high thermal conductivity and electrical insulation. This makes AlN a good material for heat sinks and heat spreaders in high power electronic applications.
It has a low dielectric constant and thermal expansion coefficient close to silicon crystal, making it an ideal choice for applications with high temperature demands. It has many uses, including in microwave power devices and semiconductor power electronics.
In addition, AlN is also used as a piezoelectric film. This is because of its high Young’s modulus and low dielectric constant.
In addition to these uses, AlN is also used in the manufacture of plastics and resins. These materials often have low thermal conductivity, so adding aluminum nitride powder to them produces potting compounds and thermal pads that have higher thermal conductivity.
