Reactive Melt Infiltration (RMI) Furnace for Carbon-Ceramic Comp

Name: Reactive Melt Infiltration (RMI) Furnace for Carbon-Ceramic Comp
Brand: YuanHang

Core Process: Utilizes Reactive Melt Infiltration (RMI) technology, where capillary forces drive the molten material to infiltrate porous preforms and undergo in-situ reactions, achieving rapid densification. Efficiency Advantage: Compared to CVI and PIP processes, RMI offers higher efficiency, producing near-fully dense carbon-ceramic composites in a single infiltration step, significantly reducing production costs. Precise Temperature Control: Maximum operating temperature reaches 2300°C, featuring AI self-learning PID technology that eliminates temperature rise lag in low-temperature ranges, ensuring exceptional temperature control accuracy.

Product details

Introduction

During the preparation process of carbon-ceramic materials, RMI (Reactive Melt Infiltration) involves heating the hot zone to above 2000°C, where precursor molecules (such as silicon) are driven by capillary forces to infiltrate the porous carbon preform and undergo chemical reactions to form a new matrix. This process, characterized by its high efficiency and low cost, has become a key technology for advancing the large-scale application of carbon-ceramic composites.
