SINTERED SILICON CARBIDE AN OUTSTANDING MATERIAL

• Boostec® SiC is a polycrystalline technical ceramic of alpha SiC type, obtained by pressureless sintering. This process yields a pure silicon carbide with no traces of free silicon. Its low residual porosity is fine and completely closed, i.e. the material is perfectly watertight. The very strong covalent Si-C bond gives Boostec® SiC exceptional physical properties that are particularly stable over time: high stiffness and hardness, low thermal expansion, high chemical and thermal stability... Its fine, homogeneous micro-structure is isotropic and virtually free of secondary phases,...

BOOSTEC® SiC, TECHNOLOGY The technology developed by Boostec enables it to serve its markets... from prototype to small production runs,with monolithic parts in SiC (coated with CVD SiC if required), SiC/SiC or SiC/metal assemblies that can take very complex shapes and reach very large dimensions. Fabrication of monolithic ceramics Isostatic pressing of large, rough shapes green machining of pressed blocks Sintering (T > 2000 °C) under protective atmosphere Grinding Lapping Final inspection Cleaning Maximum overall dimensions Cylinders Ø 1.25 m x height 0.60 m Blocks 1.70 m x 1.20 m x 0.60...

MIRRORS AND STABLE STRUCTURES for telescopes (space, ground), scientic instrumentation and high speed lasers Of the industrial materials that might be considered, Boostec® SiC achieves the best compromise between the key parameters that are common to all these applications : Space, Science and Laser Industry Scientists look for ever larger, lighter, more stable and even colder telescopes to observe the earth or the far universe with extreme precision. Boostec® SiC has shown itself indispensable to meet the mass and thermo-mechanical stability requirements of certain on-board instruments....

EQUIPMENT FOR THE SEMI-CONDUCTOR INDUSTRY The semi-conductor industry processes larger and larger silicon wafers that must be moved with increasing speed while ensuring ever more precise positioning. SiC is used to manufacture the chucks and the moving structures of the equipment dedicated to optical inspection, lithography or various other processes. Key advantages of Boostec® SiC: High stiffness Low density Low coefficient of thermal expansion, close to that of silicon High thermal conductivity Excellent chemical inertia If necessary, the sintered SiC can be given a sealed coating of CVD...

CONTINUOUS FLOW CHEMICAL Reactors and Heat Exchangers Unlike batch chemical reactors, the intensification of chemical processes enables this industry to be turned towards a decidedly greener chemistry. In the context of an agreement with Corning SAS, Boostec is developing and manufacturing high-technology chemical reactors for continuous flow systems. These new reactors represent a real technological breakthrough and reduce the production steps with improved chemical reactions in more compact and safer factories. This equipment, arising from the Corning SAS / Boostec alliance, permits the...
