Rapid Heating Flash Sintering Furnace

Introduction

This is a high-vacuum rapid-heating flash sintering furnace equipped with a flash sintering power supply. Current is introduced through electrode flanges to apply an electric field to the sample, enabling field-assisted flash sintering. Compared with traditional ceramic sintering, this process is extremely fast, energy‑saving, and beneficial for producing fine‑grained ceramics. It can be widely used for flash sintering of various ceramics. The system includes a high‑vacuum setup capable of reaching 5×10⁻⁴ Pa.
