Silicon Crystal for Neutron Sources

For more than 40 years, Sil'tronix Silicon Technologies produces its own monocrystalline silicon ingot in order to provide the highest quality for photonic applications. 


The whole Si crystals are made internally within our own factory in order to provide the flexibility requested regarding the application. We use exclusively pure silicon (9N) in order to maintain a reliable and qualitative consistency. Our purpose is to make high value products regarding individual specification to meet every user's requirement with the highest quality level.

Silicon single crystals for neutron sources

Depending on the product and its application, Sil’tronix ST provides totally customized silicon crystals for photonics application.

Nowadays, 90% of the research teams who are working in Europe on Neutron Backscattering Spectroscopy are using Silicon crystals from Sil’tronix ST. The company is really proud to announce that she is the European leader in silicon crystallography dedicated to neutron reflectivity.

On these kind of products, neutron generators need a really high quality in term of roughness, this is the reason we developed an exclusive polishing process in order to insure a roughness <2 Å (RMS) with an excellent flatness and an excellent diffraction grating.

Sil’tronix ST produces its own Cz Intrinsic single silicon crystals (with extremely pure silicon - 9N) in order to provide the best quality for X-ray diffraction analysis and insure flexibility for low and medium volume.

Because we growth our own monocrystalline silicon ingots, the silicon crystal structure is perfectly mastered in order to machine the material with a really good orientation accuracy (up to 0,02°).

Over decades of experiences we developed particular know how to provide totally customized Si crystals base on customers’ requests (technical drawing, chat with our technical engineers and doctors, …) for neutron scattering, light sources, …
