  2. Ultra-high temperature ceramic - Wikipedia

    en.wikipedia.org/wiki/Ultra-high_temperature_ceramic

    Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking ...

    However, above a certain temperature (it depends on environmental conditions of oxygen partial pressure) starts the active oxidation of silicon carbide matrix to gaseous silicon monoxide (SiO (g)), consequently loss of protection from further oxidation, which leads the material to an uncontrolled and fast erosion. For this reason C/SiC and SiC ...

    en.wikipedia.org/wiki/Yttria-stabilized_zirconia

    The cementation occurs on removal of water. The resulting ceramic material is suitable for very high-temperature applications. YSZ doped with rare-earth materials can act as a thermographic phosphor and a luminescent material. [14] Historically used for glowing rods in Nernst lamps. As a high-temperature coating, produced by ZYP Coatings, Inc.

  5. Ceramic - Wikipedia

    en.wikipedia.org/wiki/Ceramic

    A ceramic is any of the various hard, brittle, heat-resistant, and corrosion-resistant materials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. [1] [2] Common examples are earthenware, porcelain, and brick.

  6. Zirconium diboride - Wikipedia

    en.wikipedia.org/wiki/Zirconium_diboride

    ZrB 2 is an ultra-high temperature ceramic (UHTC) with a melting point of 3246 °C. This along with its relatively low density of ~6.09 g/cm 3 (measured density may be higher due to hafnium impurities) and good high temperature strength makes it a candidate for high temperature aerospace applications such as hypersonic flight or rocket ...

    CMC are characterised by high operating temperatures, corrosion resistance and damage tolerance and are therefore used to improve high-temperature processes. In addition, processes such as 3D printing are also available at the Fraunhofer Centre HTL for the production of metal and ceramic components with complex geometries.

  8. Ceramic matrix composite - Wikipedia

    en.wikipedia.org/wiki/Ceramic_matrix_composite

    An example of CMC manufacture, which was introduced for the production of ceramic brake discs, is the reaction of silicon with a porous preform of C/C. [14] The process temperature is above 1,414 °C (2,577 °F), that is above the melting point of silicon, and the process conditions are controlled such that the carbon fibers of the C/C-preform ...

  9. High-temperature superconductivity - Wikipedia

    en.wikipedia.org/wiki/High-temperature...

    The second class of high-temperature superconductors in the practical classification is the iron-based compounds. [8] [9] Magnesium diboride is sometimes included in high-temperature superconductors: It is relatively simple to manufacture, but it superconducts only below 39 K (−234.2 °C), which makes it unsuitable for liquid nitrogen cooling.
