Mersen Graphite - Rigid Insulation, CALCARB CBCF Insulation

Rigid Insulation

Experts in high-temperature insulation

Mersen acquired CALCARB in 2009. CALCARB CBCF insulation enables the perfect protection and regulation for very high-temperature furnaces from 1,000°C up to 3,000°C. As an expert in composite or graphite refractory materials and high-temperature insulation, Mersen Graphite sells “machined to design” solutions, providing turnkey service capabilities.

We can supply CBCF material in various forms from foil backed board stock for sintering furnaces, to barrel stave, CWC (cylinder within a cylinder), and formed cylinders up to 55” in diameter for vacuum furnaces.

To increase the life and performance of CBCF insulation, Mersen offers these enhancements:

  • Calcoat: A standard graphite paint that inhibits dusting by sealing all coated surfaces. It offers a limited erosion resistance. 
  • Calfoil: A high purity graphite foil protection that inhibits also dusting, enabling a better temperature uniformity along plane of foil.
  • Calcoat CVD: A pyrocarbon outer layer that is applied to all finished surfaces of machined parts to offer erosion protection and a barrier against impregnation from process vapors.
  • Innovative SIC Protection: In some specific conditions, like hydrogenated atmosphere over 1,000°C, carbon fibers are corroded by the medium. As insulation parts are often the critical part of such a process, the silicon carbide infiltration provides an unparalleled advantage.  Mersen’s unique expertise in this field can help to reduce maintenance downtime of your process by extending the insulation service life.

pure graphite for photovoltaic panels

Photovoltaic

Innovation & efficiency for PV energy

Our pure HCL turn-key systems are used to produce trichlorosilane (TCS) a key component for manufacturing polysilicon. Plus, our ultra-pure graphite equipment enables manufacturers of polysilicon, the principal component in photovoltaic panels, to increase their efficiency while cutting their costs. By helping to unlock competitive gains, we are playing a key role in the development of this industry.

Polysilicon is the key material used in photovoltaic cells whose purification requires large amount of our equipments:

  • Hydro Chloric acid stripper for the silanes production
  • Graphite equipments for Siemens, FBR and UMG processes

Polysilicon chunks are then melted in high temperature furnaces to produce the round- or square-section ingots that will be used for making photovoltaic cells. Three main processes can be used to transform polysilicon into solar cells:

  • CZ process for mono-crystalline cells
  • DSS process for multi-crystalline cells
  • Ribbon growth for thin multi-crystalline cells

Mersen Graphite provides long lasting process solutions to achieve the best solar cell efficiency and to reduce the energy consumption in the process.

In the transmission of power from the solar panels to the grid, Mersen Graphite provides electrical components for circuit protection (Current, Voltage surge and Cooling for power electronics).

Photovoltaic Applications: 

Connectors, Heaters, Shields, Pedestals, High Temperature Thermal Insulation Packs

Mersen Graphite - Graphite Coatings / Graphite Impregnation

Coatings & Impregnations

Ensuring the preservation of your Graphite Equipment with our coated products

Mersen's products can be coated with a thin layer of Pyrolitic Carbon thereby reducing the material's permeability to reactive products to a minimum, particularly for semi-conductor applications. In order to further enhance the resistance to process reagents, Mersen Graphite proposes core impregnation with resin to reduce porosities.

Mersen has also mastered the deposition of Silicon Carbide Thin Films which provide unequalled protection of graphite equipment in particularly harsh environments. Mersen also supplies coated products for Semiconductor, MOCVD, and Photovoltaic industries.

  • SIC Coated Graphite for thin film applications

 

Services

CVD Silicon Carbide Coating

Mersen's products are coated with a uniform impervious CVD deposition of Silicon Carbide. The result is a high-quality part that is virtually inert to all process gases and chemicals. An excellent CTE match is maintained between the graphite substrate and the silicon carbide coating – an important feature that assures greater stability and longer life.

CVD Pyrolytic Graphite Coating

Mersen's CVD Pyrolytic Graphite is an ultra-pure coating that provides high density, strength and hardness along with very low porosity which is virtually impermeable to fluids and gases. This unique coating features varying properties dependent on crystallographic orientation.

Design & Engineering

Mersen also has extensive market, industry, and application knowledge that can be used to provide guidance in designing CVD-coated components that meet your specific requirements.

Vitreous Carbon Impregnation

This process was developed to reduce particle emissions and the vacuum outgassing of materials, particularly for semi-conductor applications.
