Single Material Joining of SiliconInfiltrated Silicon Carbide (SiSiC)
H.C. Starck Ceramics is an expert of technical ceramics products and a leading producer of components made from
oxide and non-oxide ceramics.
SiSiC from H.C. Starck Ceramics enables joining with excellent material and mechanical properties for the final product.
In the process, the individual components are bonded together using the same material. This is a leading edge for the
production of large-size components, parts with undercuts and designs with cooling channels.
Our SiSiC advantages:
>> Production of large-size components
>> High stiffness
>> Extremely homogeneous material
>> High strength
>> Joining areas with identical material properties,
>> Low coefficient of thermal expansion
such as E modulus and strength
>> Superior reliability
>> Material without contamination of
the bulk material with impurities
We produce components from SiSiC with the maximum dimensions of approximately 950 x 950 x 500 mm.
