Low Thermal Expansion Ceramics

Extremely low thermal expansion zerodur the extremely low thermal expansion glass ceramic from schott delivers extremely high precision for many challenging high tech applications some of the applications for zerodur include ic interated circuit and fpd flat panel display lithography high precision metrology and astronomy all demanding applications in which geometrical shape and.

Low thermal expansion ceramics.

Fine ceramics also known as advanced ceramics have low coefficients of thermal expansion less than half those of stainless steels. 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. Also due to excellent heat insulation with small dimensional changes from heat adceram cs can cope with abrupt temperature changes. Toto s low thermal expansion ceramics have light weight and low cte to contribute to improvements in overall equipment performance.

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. When a substance is heated molecules begin to vibrate and move more usually creating more distance between themselves. Thermal expansion is the tendency of matter to change its shape area volume and density in response to a change in temperature usually not including phase transitions. Cordierite cordierite is an extremely low thermal expansion ceramic which is ideal for light weight designs of mirrors and telescopes.

In the video below dr. Our diffusion bonding makes it possible to mold complex hollow shapes. The coefficient ratio of thermal expansion indicates how much a material expands per 1 2 2 rise in temperature. 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.

Nexcera ultra low thermal expansion ceramics. Expansion values vary depending on the material being heated. By utilizing dense cordierite with a low thermal expansion coefficient deformation due to temperature change is suppressed. Temperature is a monotonic function of the average molecular kinetic energy of a substance.
