Ultra high temperature ceramics uhtcs are a class of refractory ceramics that offer excellent stability at temperatures exceeding 2000 c being investigated as possible thermal protection system tps materials coatings for materials subjected to high temperatures and bulk materials for heating elements.
Ceramics for high heat applications.
This issue can be solved by using high temperature heat pipes with a ceramic pipe container.
This paper outlines the results of the ongoing work on the design of such heat.
In very high speed applications heat from friction during rolling can cause problems for metal bearings which are reduced by the use of ceramics.
Technical ceramic materials stand out due to unique set of properties such as high resistance to corrosion erosion and wear electrical and thermal insulation at high temperatures and high heat resistance.
These unique characteristics can be further developed optimised and matched for use in industrial applications.
In some cases their electricity insulating properties may also be valuable in bearings.
Ceramics are also more chemically resistant and can be used in wet environments where steel bearings would rust.
State of the art the heat pipe technology is well known for very high heat fluxes.
Broadly speaking uhtcs are borides carbides nitrides and oxides of early.
