    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 or breaking.

    For most of its history, Grace's main business was cargo shipping, operating the Grace Line. To move cargo from Peru to North America and Europe, including guano and sugar, and noticing the need for other goods to be traded, William Grace founded a shipping division. Grace Line began service in 1882, [18] with ports of call between Peru and New ...

    Additionally, from 1969 to 1971, the 3 MW Ultra-High Temperature Reactor Experiment (UHTREX) was operated by Los Alamos National Laboratory to develop the technology of high-temperature gas-cooled reactors. [17] In UHTREX, unlike HTGR reactors, helium coolant contacted nuclear fuel directly, reaching temperatures in excess of 1300 °C.

    en.wikipedia.org/wiki/Ultra-high-temperature...

    Metamorphism of crustal rocks in which peak temperature exceeds 900 °C, recognized either by robust thermobarometry or by the presence of a diagnostic mineral assemblage in an appropriate bulk composition and oxidation state, such as assemblages with orthopyroxene + sillimanite + quartz, sapphirine + quartz or spinel + quartz, generally at pressure conditions of sillimanite stability in ...

    A Tetra Pak ultra-pasteurization line. Ultra-high temperature processing ( UHT ), ultra-heat treatment , or ultra-pasteurization [ 1 ] is a food processing technology that sterilizes liquid food by heating it above 140 °C (284 °F) – the temperature required to kill bacterial endospores – for two to five seconds.
