Glass-like Carbon “Carbon material with excellent chemical and corrosion resistance”
Glass-like Carbon is a type of carbon material with a proven track record for use in semiconductor manufacturing system components. High purity is also possible.
In addition to the general properties of carbon materials such as chemical resistance, corrosion resistance, heat resistance, and electrical conductivity, glass-like carbon has the characteristics of gas and liquid impermeability, isotropy, acid resistance, and no dust generation. Because of these excellent characteristics, glass-like carbon is mainly used as a component in a semiconductor manufacturing system. 【Common Characteristics of Glass-like Carbon】 ・Chemical resistance, corrosion resistance, heat resistance, electrical conductivity, and dust-free ・Impermeability to gases and liquids ・High purity (high purity is possible by a special treatment in the manufacturing process) ・High heat resistance, high X-ray permeability 【Characteristics of Glass-like Carbon Beads】 ・Spherical carbon material with a smooth surface, which can be used as filler or porous material for ceramics, etc. ・Low thermal expansion and high thermal shock resistance. ・Dense isotropic structure without pores ・Central grain size 100μm, 200μm *For more details, please contact us or download the catalog.
