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 Semiconductor 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
