Glassy Carbon — Thermal Expansion

The thermal expansion of the glassy carbon sample shows a linear range up to 2300°C and subsequently a strong increase of the expansion coefficient up to 2700°C. The sharp bend in the expansion curve at 2326°C shows the maximum sintering temperature which was applied in the manufacturing process of this carbon product. (measurement with DIL 402 E)

DIL 402 E/7

The DIL 402 E dilatometer can be operated up to 2400°C or 2800°C with an optical pyrometer and a graphite furnace.
