Non Oxide Ceramics

Non oxide ceramics 9 0 introduction non oxide ceramics include carbides nitrides borides silicides and others.

Non oxide ceramics. 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. Non oxide glasses this session welcomes presentations covering new developments in chalcogenide halide metallic organic glasses and all other types of non oxide glasses. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. The properties of the non oxide ceramic silicon nitride si3n4 make this ceramtec ceramic the material of choice for extremely demanding applications.

Their applications range from superhard abrasives b4c bn and cutting tools wc to rocket nozzles tib2 electrodes for metal melts zrb2 and heating elements mosi2 the most important structural. The sialons are particularly important because they occur as several polymorphs with different crystal structures and a range of. Ceramco can produce oem ceramic parts from virtually any ceramic powder or formulation thereof. Topics of interest include structural characterization structure property relationship novel processing methods compositional trends and advances in physical properties.

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. 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. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Among other features si3n4 ceramics are resistant to impact and strikes thanks to their very high fracture toughness.

Non oxide ceramic polycrystals with conductivities close to those of single crystals have been developed through the advances in ceramic processing. Also we work with non oxide materials. As with the refractory ceramics above these other materials developed and or used for previous applications are thoroughly documented and available to solve the challenge of future oem ceramic parts orders. Types of non oxide ceramics.

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. In recent years the thermal conductivity exceeding 150w m 1 k 1 has been reported for β si 3 n 4 ceramics joining a group of high thermal conductivity solids. Silicon nitride and silicon carbide two commonly used ceramic non oxide fibers offer high heat resistance.
