- SiC business of Gunze
In 1975, Professor Seishi YAJIMA, Tohoku University, developed a method for the production of SiC fibers from organic silicon polymer. More than 30 years later, the application capabilities of SiC fibers have shown a rapid expansion, and at present, SiC fibers with a heat resistance of around 1800 degrees are being developed. However, in spite of these excellent capabilities, SiC fibers with their high crystalline and chemical stoichiometric composition at present are produced only in small quantities and generally are not used widely because their production process requires a high degree of technology. Based on fiber processing technology cultivated over more than 110 years, Gunze has established a joint research and development system with IEST and the Muroran Institute of Technology, and is advancing the development of application of SiC fibers and SiC/SiC composite materials in a wide range of fields by developing a mass production process.
SiC (Silicon Carbide) is a chemical compound in which Si (silicon) and C (carbide) are combined one to one, and it practically does not exist naturally. In 1884, E. G. Acheson first synthesized SiC from clay and graphite, then sold it commercially as a polishing agent.
As SiC has particularly good heat resistance and low activation properties at high temperatures, there are expectations related to nuclear power and aerospace applications. Recently, it has attracted attention as a high-temperature semiconductor material (power devices) which can be used at temperatures close to 500℃ and for related materials.
Manufacturing process for SiC and SiC composites materials
Gunze offers various process materials matching the customer needs. SiC and SiC composites materials also are available in various grades with a heat resistance matching the intended purpose; also, and client-specific solutions are offered.
