Low Thermal Expansion Ceramics

The forming capabilities of kyocera allow for a more efficient processing and light weighting while the material properties of cordierite co720 such as high stiffness and long term dimensional stability serve functional advantages over low thermal.

Low thermal expansion ceramics.

Low thermal expansion ceramic mirrors highly rigid and extremely thin with reduced weight. By utilizing dense cordierite with a low thermal expansion coefficient deformation due to temperature change is suppressed. Expansion values vary depending on the material being heated. Also due to excellent heat insulation with small dimensional changes from heat adceram cs can cope with abrupt temperature changes.

Nexcera is an ultra low thermal expansion ceramic with a cordierite base 2mgo 2al 2 o 3 5sio 2 it features zero expansion near room temperature and is stronger and more durable than low thermal expansion glass. Nexcera ultra low thermal expansion ceramics. Today our low expansion ceramics are used in exhaust gas treatment applications to help reduce harmful emissions from cars and trucks. Cordierite cordierite is an extremely low thermal expansion ceramic which is ideal for light weight designs of mirrors and telescopes.

Toto s low thermal expansion ceramics have light weight and low cte to contribute to improvements in overall equipment performance. In the video below dr. The coefficient ratio of thermal expansion indicates how much a material expands per 1 2 2 rise in temperature. Our diffusion bonding makes it possible to mold complex hollow shapes.

Adceram cs low thermal expansion and heat insulating ceramics adceram cs is light weight and has unique thermal characteristics a low coefficient of thermal expansion low heat conductivity and high thermal shock resistance. Fine ceramics also known as advanced ceramics have low coefficients of thermal expansion less than half those of stainless steels. Due to their low thermal expansion often close to zero las glass ceramic has been widely used for more than 60 years in telescopes mirrors 18 optical precision systems 19 cooktops 20. When a substance is heated molecules begin to vibrate and move more usually creating more distance between themselves.
