Effects of additive gases on radio-frequency plasma sintering of alumina

  • Ming Yung Chen
  • D. L. Johnson


Pure and 0.25 wt% MgO-doped alumina powder compacts were sintered using a radio-frequency induction-coupled argon plasma. The effects of additive oxygen, hydrogen, nitrogen and water were investigated by injecting varying amounts of each gas during sintering. The addition of diatomic gases or water vapour to argon gas during plasma sintering increased the temperature and sintered density of the specimens. Water vapour showed the strongest effect, followed by hydrogen, nitrogen and then oxygen. The presence of MgO dopant resulted in greater density and a lower sample temperature than those of the pure material.
