Abstract

A structure of composite crucibles and a high temperature adiabatic method in an arc heating process are disclosed. The structure may include a conventional water-cooled copper platform on which one or more graphite platform(s) are disposed and the topmost graphite platform is configured for disposing one or more metallic specimen(s). When arc smelts the metallic specimen(s) in the furnace in vacuum, and the heat of the metallic specimen(s) is transferred to the graphite platform, the graphite platform can reduce heat loss and improve heat preservation so as to cause the metallic specimen(s) to remain stable for the process of heating and melting to complete. The heat of the graphite platform is further transferred to the copper platform for lowering the temperature of the graphite platform.
