Abstract

Highly textured hexagonal boron nitride (h-BN) matrix ceramics with Al2O3 and Y2O3 as sintered additives were fabricated by digital light processing (DLP), stereolithography (SLA) 3D pringting and hotpress (HP) sintering. The orientation degree of sintered h-BN-YAG ceramic was evaluated by X-ray diffraction and pole figures. Due to the highly textured character, the BN-YAG ceramic shows obvious anisotropic thermal properties. By using the rearrangement of crystal grains during photocuring, a textured ceramic having high orientation degree can be prepared under a short holding time and a low sintering pressure.

Keywords: textured, hexagonal boron nitride, pole figures, thermal properties
