Advanced Ceramics for
High-Tech Industries
Products : Insulators and structural parts for laser & optoelectronic systems
Ceramic components offer significant advantages over metal and plastic parts. They retain their full dimensional stability at high temperatures – well above 1000°c. They can dissipate heat in a very efficient way. They show a high wear resistance to corrosive environment. They are extremely good electrical insulators. They do not outgas in vacuum.
Applications
Insulators and structural parts made from advanced ceramics are used to insulate, resist to corrosive gases and ensure good dimensional stability in the following applications :
- diode lasers
- semiconductor lasers
- solid-state lasers
- gas lasers - CO2 & Excimer
- fibre lasers
- optoelectronic devices
- infra-red detectors
Products
Mirocertec offers the following customised components :
Insulators
- thin substrates for laser or optoelectronic devices
- electrode tubes & plates for ionisation chambers
- high-voltage insulators
Structural parts
- optical component holders
- sensor components
- optical fibre holders
Materials
For these applications, we mainly use the following advanced ceramics :
- sintered aluminium nitride – AlN – due to its higher thermal dissipation but still offering perfect electrical insulation
- alumina for applications where electrical insulation is solely required
- silicon carbide due to its higher wear resistance, its ability to develop fine surface finish and its good thermal conductivity
- Macor ® for a good thermal as well as electrical insulation
- silica and sapphire as they can also be clear polished
Thin-film metallising
Thin-film metallised layers made under vacuum can be deposited on these ceramic heat sinks and electrical insulators in addition to our precision grinding. Microcertec can offer the following thin-film metallised layers for your components to be bonded or brazed :
- titanium - platinum – gold
- chromium - nickel - gold
- copper, aluminium, silver, or indium
- resistive layers - Ta2N.
These thin-film metallised layers can be uniquely made on 3D components. They can be ablated afterwards by laser micro-machining in order to create electrical paths or insulating areas.
