Precision Machining
Bay Carbon has a complete modern machining facility specializing in precision machining of high purity graphite. Normal machine tolerances are +/- 75 microns, for special application +/- 5 microns can be achieved and certified by CMM. Our ability to quickly turn around your graphite needs from design to the final product will give your company the advantage in bringing your product to market.
Silicon Carbide Coating
Bay Carbon has over 40 years of experience producing high purity, iso-molded graphite susceptors for CVD processes. All graphite for susceptor applications is purified using Bay Carbon proprietary purification technology and tested using DC Arc optical emission spectroscopy to insure purity levels that are consistent with semiconductor applications. The graphite susceptor products are available with a thermal coefficient matched CVD silicon carbide protective coating. Each SiC coated graphite susceptor is packaged in sealed clean room compatible poly-bags and shipped in protective enclosures in individual containers.
Tantalum Carbide Coating
Tantalum Carbide is a compound of tantalum and carbon with a chemical formula TaC. The coating is an extremely hard, refractory ceramic material, with a metallic electrical conductivity. The melting point of Tantalum Carbides peaks at about 3880°C depending on purity and has one of the highest melting points among the binary compounds. This makes it an attractive alternative when higher temperature demands exceed performance capabilities of CVD Silicon carbide coated graphites.
DC Arc Direct Analysis
The DC Arc technique has been relied upon for decades as a tool for the direct analysis of a wide range of solid materials. The earliest systems, many of which are still in use today, were photographic plate spectrographs. These systems offered the advantage of providing a permanent photographic record a samples spectrum, but also carried with it the cumbersome need to view and interpret photographic plates. These early generation instruments were replaced, first by PMT-based simultaneous spectrometers and then CID based DC Arc spectrometers, each with their own strengths and weaknesses.
Graphene
Graphene is a form of carbon which has emerged into one of the most studied 2-D electronic solids in materials research. Still early in its development, many researchers have demonstrated new and exciting performance milestones with graphene material forms and devices in electronic, chemical and mechanical product applications.
