Overview

SiC tubes have emerged as potential candidate material in the area of concentrated solar power generation, heat exchangers for recovery of heat from industrial waste, fuel cladding in nuclear reactors because of superior thermos-mechanical properties, high thermal conductivity, resistance to chemical attack and nuclear radiation. ARCI has developed the process for producing SiC tube by extrusion as well as cold iso-static pressing technique followed by sintering.

Key Features

  • Extrusion press is capable of producing long tubes of different diameter and wall thickness.  
  • High production rate.
  • Process flexibility to produce dense and porous SiC tubes. 

Potential Applications

  • Tubular solar receiver in CSP technology.
  • Heat exchanger.
  • Nuclear fuel cladding tubes.  
  • Support tubes in membrane separation. 

Status

  • SiC tubes produced by both extrusion and cold-isostatic pressing have been produced and properties tubes are being evaluated.
