Non Oxide Ceramic Materials

Ceramco can produce oem ceramic parts from virtually any ceramic powder or formulation thereof.

Non oxide ceramic materials. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. The sialons are particularly important because they occur as several polymorphs with different crystal structures and a range of. Sic is the most widely used non oxide ceramic material. Fired ceramic that contains no oxygen in the crystal structure.

Hundreds of different types of these materials exist dozens of boron derivatives alone. Aluminum nitride aln boron carbide b 4 c carbon carbon graphite. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.

The non oxide ceramic silicon carbide sisic or ssic is a ceramic material that is as hard as diamond and features many other important characteristics. As with the refractory ceramics above these other materials developed and or used for. Non oxide ceramics aluminum nitride aln ceramic material with very high thermal conductivity. Non oxide ceramics such as silicon nitride and the various silicon aluminium nitride sialon compounds are important high technology materials with applications as wear resistant engineering components and cutting tools because of their hardness and toughness.

Types of non oxide ceramics. Most structural and refractory ceramic materials are based on oxide compounds. Thus the process parameters must be optimized thoroughly with regard to heat treatment. Most sic α sic is still synthesized via the acheson process carbothermal reaction of quartz.

In the production of non oxide ceramics the heat treatment is an important step of the production process it determines the product quality but also adds to manufacturing costs. This grouping contains those that are not. Silicon nitride and silicon carbide two commonly used ceramic non oxide fibers offer high heat resistance. Examples are boron nitride bn and silicon barbide sic.

Aluminum nitride aln is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. These products exhibit a range of amazing properties including hardness resistance to corrosion and heat compressive strength etc. Also we work with non oxide materials. It was first synthesized by acheson in 1891 by heating a mixture of clay and carbon 1600 c in a carbon arc carborundum a name still used today for abrasive and refractory grade sic.
