• Brief description: 

     The Spark plasma sintering system is mainly used for preparing metallic materials, ceramic materials, composite materials, nanobulk materials, amorphous bulk materials, and gradient materials. Additionally, SPS equipment enables the fabrication of highly specialized new materials—such as nanomaterials, functionally gradient materials, composite materials, tungsten carbide, silicon nitride, silicon carbide, and other hard materials, as well as structural ceramics and functional ceramics—all without significant grain growth. This facilitates the sustained development of research in relevant material fields.
