Double Chamber Graphitization Furnace

This equipment is a graphitization furnace that can raise the temperature up to 2500℃ or higher at inert gas atmosphere of atmospheric or reduced pressure. It is composed of a charging/cooling chamber and a heating chamber, and the charging/cooling chamber has a temperature ranging from room temperature to 600℃ while the heating chamber ranging from 600 to 2500℃. The samples are moving from the charging/cooling chamber → the heating chamber → the charging/cooling chamber in a vacuum or nitrogen atmosphere. sequentially being dried, heat treated, and cooled naturally or in forced nitrogen flow.

Features

Reduce the total process
time to less than 1/2 by forced
cooling with nitrogen circulation
at the 600℃ to RT cooling step.
Save energy consumption by
maintaining the temperature of
the heating chamber above 600℃,
without the cycle of RT to 600℃.
Extend the life of expensive
furnace materials such as heaters
and insulation by blocking the
heating chamber’s contact with external air.
Prevent contamination of
the heating chamber by moisture,
binder or etc. through using
the charging/cooling chamber as a
drying or de-waxing chamber.
