Sintered silicon carbide is the best material for space optical assemblies

Sintered SiC is an homogeneous material, with an isotropic microstructure
The material shows a very high specific stiffness and a very high stability (low sensitivity to thermal gradients)
It allows to obtain very stiff, lightweight and stable structural parts and reflectors
It can be polished with the standard glass polishing techniques
The industrial process used by BOOSTEC has been experienced during more than 20 years of mass production (automotive, chemical engineering, ...)
Its physical properties are furthermorereproducible in time, from batch to batch
