The SPS (Spark Plasma Sintering) method is a purely domestic technology that was developed and nurtured in Japan as one of the pulse electric field processing techniques. It is a next-generation material synthesis and processing method that enables sintering and joining of various materials, including powders and solids. It targets various processes such as sintering, joining, molding, synthesis, and surface modification. It encompasses a very wide range of target materials, including metals, ceramics, polymers, composite materials, and multi-element materials. 【Features】 ■ High-speed heating (over 1000°C/min) ■ Purification and activation of particle surfaces ■ Controlled particle growth sintering ■ Wide temperature range (from room temperature to ultra-high temperature regions exceeding 2000°C) ■ Easy density control (from porous bodies to dense bodies) ■ Temperature gradient sintering *For more details, please refer to the PDF document or feel free to contact us.
