Ceramics For High Heat Applications

This issue can be solved by using high temperature heat pipes with a ceramic pipe container.

Ceramics for high heat applications.

State of the art the heat pipe technology is well known for very high heat fluxes. State of the art for high temperature heat pipes are nickel based alloys as container material and alkali metals as working fluids cs k na li. Similarly in applications closer to us such as infrared heaters in modern houses high temperature furnaces barbeque grills and household heating appliances glass ceramics stand out with their sleek stylish look the versatile material options and their ability to resist different influences. These unique characteristics can be further developed optimised and matched for use in industrial applications.

Ceramics are also more chemically resistant and can be used in wet environments where steel bearings would rust. In very high speed applications heat from friction during rolling can cause problems for metal bearings which are reduced by the use of ceramics. This paper outlines the results of the ongoing work on the design of such heat. 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.

In some cases their electricity insulating properties may also be valuable in bearings.
