Abstract

Vacuum sintering apparatus are disclosed. In some embodiments, a vacuum sintering apparatus includes a vacuum cavity body, a power supply assembly, an electrode assembly, a heating body assembly, and a heat-preservation assembly. The heat-preservation assembly is provided within a vacuum chamber. The heat-preservation assembly includes a fixing bracket and a carbon felt heat-preservation layer. The fixing bracket is provided in a square shape or an annular shape. The carbon felt heat-preservation layer is laid around the fixing bracket. The heating body assembly is provided within a zone surrounded by the carbon felt heat-preservation layer. The heating body assembly includes two groups of unidirectional heating channels. The unidirectional heating channel is in an unenclosed square shape or an unenclosed annular shape. The two groups of unidirectional heating channels are connected in series by a connecting member. The connecting member is made of a conductive material.
