High Purity Applications
Over the past decade natural graphite has been refined into products such as expanded graphite, exfoliated graphite, and graphite foil. Each of the materials has a wide range of applications in sectors such as high temperature gaskets in automotive applications, thermal management in electronics, and high strength components in aerospace products. As previously noted, it is graphene that is being called the Mother of All Graphites these days. Scientists and companies are only just beginning to understand its full range of capabilities whether it be solar cells, liquid crystal displays, or semiconductors. Whatever the application, it is widely seen as a natural graphite growth sector for many years to come.
Semiconductor Materials and Quartz
Semiconductor technology demands constant innovation and ultrahigh-purity materials from suppliers. Products made from high-purity fine-grain graphite meet these requirements. Typical examples are the development of materials for wafer production processes, as well as coatings that enhance the purity of the next semiconductor generation while extending our materials’ service life at the same time. The following are products using graphite in semiconductor manufacturing:
- Electrodes and heating elements for manufacturing high purity quartz glass products
- Heaters and shields for manufacturing optical fibers
- Blanks and graphite electrodes for polycrystalline silicon deposition
- Components made of high purity graphite, carbon/carbon, soft and rigid felt for crystal growing of silicon, germanium and III/IV composites (e.g. susceptors, heaters, heat shields, current connecting parts)
- Slicing beams made of carbon and graphite for cutting monocrystal rods
- Graphite boats for zone refining of semiconductor materials
- Graphite boats for reduction heating of germanium oxide
- Graphite and C/C crucibles and boats for melting high purity metals or semiconductor materials
- Brushes, Anodes, Cathodes, Current Collectors, Sliding Contacts, EDM Electrodes, Resistors, Brazing Tips, Heaters, Seed Holders, Susceptors, Wafer Carriers, Purified Components, Heaters, Crucibles, Seed Rods, Bolts, Power Connectors, Diffusion plates

 The City of Windsor has agreed to purchase up to 10 electric buses (ebuses) from BYD. This deal could potentially lead to BYD manufacturing ebuses in the Ontario region. The first electric bicycle (ebike) made in Canada will make its debut on city streets this spring.
The Procycle eVox ebike is targeting customers that are cycling enthusiasts over 50 years of
age and young urban professionals.
IBM is onto a potential breakthrough lithium-air battery that can theoretically store 1,000x more energy than a lithium-ion (li-ion) battery. The battery literally breathes in air to produce more energy as an EV is driven which extends the range of a single charge.
Canada’s first public network of charging stations is about to power up. By March, the first 90 240-volt charging stations should be operating at 60 sites in the Montreal and Quebec City regions. Toyota and BMW announced a partnership to share eco-friendly technologies, including in the joint development of lithium-ion (li-ion) batteries for next-generation electric vehicles (EVs). The organizations will share development costs for batteries for EVs as part of plans to roll out battery-powered vehicles.
Researchers at Northwestern University have developed an electrode that could allow conventional li-ion batteries to hold a charge 10 times greater than current technology. The researchers sandwiched clusters of silicon between the graphene sheets that could eliminate or marginalize the fragmentation.
Nissan is aiming to sell 1.5 million electric vehicles (EVs) around the world by 2016. The company plans to add an additional seven models across the Nissan and Renault group.
NAATBatt September Issue Japan's three carbon fiber suppliers (Toray Industries, Toho Tenax and Mitsubishi Rayon) are leading a drive to adopt the lightweight carbon fiber (CF) for automobile According to BMW, CF is used for about 30% of the vehicle's body, cutting its weight by about 100 kilograms.
NAATBatt October Issue Johnson Controls is investing $100 million to build a Start-Stop vehicle battery plant in China. The plant will supply global and local automakers in Asia and is expected to start production in early 2013. The company plans to produce an annual capacity of 2.4 million Start-Stop batteries by 2015 for local and global automakers. President Barack Obama toured the Johnson Controls-Saft advanced battery center, the first facility in the United States to produce lithium-ion (li-ion) battery cells and systems for electric vehicles (EVs). Johnson Controls has also committed to opening a 2nd li-ion plant in the U.S.
