Ceramic Components for Lasers and Optoelectronic Devices
Ceramic components offer significant advantages over metal and plastic parts. They retain their full dimensional stability at high temperatures – well above 1000°C. They show a high-wear resistance. They are extremely good electrical insulators. They do not outgas in vacuum environment. Ceramics are inert materials and are resistant to many gases and chemicals. The majority of ceramics show high thermal insulating properties but conversly a few ...

Insulators for Lasers
Advanced ceramics are widely used in laser systems due to their combined properties of very good electrical insulation - high voltage and high current - and resistance to gas and plasma corrosion. Their resistance to temperature variations, to high temperatures, as well as their very low thermal expansion make them reliable materials to manufacture precision ...

Model CI3D - Ceramic 3D Interconnect Devices
Microelectronic circuits continuously require new packaging technologies. Ceramic substrates are widely used in this field for their good dimension stability, high electrical insulation as well as their resistance to high temperature. But it is now possible to create microelectronic circuits on 3D carriers made with ceramics. This new type of component integrates electrical and mechanical functions on a same carrier, which gives a wider scope in terms of ...

Model ZrO2 - Zirconia Grades
Zirconia grades are various. They differentiate from each other by the nature of the stabilising agent which is used. In its pure form, zirconia is not stable. Magnesia-partially-stabilised zirconia (MgO-PSZ) and yttria-partially stabilised zirconia (Y-TZP) in particular offer an outstanding resistance to mechanical shocks as well as to flexural load, because of their high fracture toughness and relative “ elasticity ”. These two zirconias are ...

Model Si3N4 - Silicon Nitride
Silicon nitride is one of the hardest ceramics but also one of the most resistant. Si3N4 is mainly used in severe environments which combine extreme temperatures with abrasive and/or corrosive medium. Silicon nitride can be of different grades : sintered, hot pressed or reaction ...
