Description:

Achieving an (001) orientation-aligned structure in the YVO4 green bodies by colloidal processing with a strong magnetic field can enhance optical properties the translucent YVO4 ceramics fabricated by a spark-plasma-sintering (SPS) technique. YVO4 green bodies with orientation along the (001) direction is successfully attained from well-dispersed and highly stable YVO4 slurry containing 15 vol% YVO4 nanopowders prepared at 1wt% of dispersant under pH > 9. By designing the (001) texture of YVO4 with aligning the slip casting direction parallel to the magnetic field B during the slip casting, the YVO4 SPSed at a temperature of T = 1300 oC gained much higher transmittance than that of non-textured random YVO4, indicating that controlling the microstructure by colloidal processing with a strong magnetic field is an effective approach to improving the optical properties of YVO4 ceramics.
