Graphitization at up to 3000 °C with Chamber Furnaces

Aug 08, 2017 · Usually, debinding is performed in controlled inert gas atmosphere conditions at temperatures below 800 °C with numerous dwell time steps for debinding various kinds of impurities. After carbonization is completed, the furnace will automatically ramp up to 3000 °C (based on the furnace model) for final graphitization.

High energy ball milling process for nanomaterial synthesis

In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for high-energy ball milling. However, using optimized milling speed and milling time may effectively reduce the contamination.
