Abstract

Porous Si ₃N ₄ ceramic with a porosity higher than 70% is fabricated by a technique combining three-dimensional printing and pressureless sintering. Using chemical vapor infiltration (CVI) of Si ₃N ₄, the mechanical properties of the porous Si ₃N ₄ ceramic are clearly improved by increases in the connection strength among β-Si ₃N ₄ particles and the loading ability of β-Si ₃N ₄ particles. The porous Si ₃N ₄ ceramic after CVI of Si ₃N ₄ is an excellent wave-transparent material due to its good mechanical properties and excellent dielectric properties.
