Image of Glass-like Carbon

Glass-like Carbon has a pore-free and amorphous structure like that of glass and combines the features of carbon with those of glass.
 It has a high corrosion resistance, high hardness, high uniformity, and less particle.
 Considering the characteristics, Glass-like Carbon is used in Semiconducor Manufacturing Process, heat treatment Process etc.

Features

  • High Thermal Resistance
  • High Corrosion Resistance
  • High Erosion Resistance
  • High Uniformity
  • High Hardness
  • High Purity
  • Low Coefficient of thermal expansion
