| Abstract |
Camphene and tert-butyl alcohol (TBA) crystals are used as sublimable vehicles in a freeze casting process to fabricate porous W with distinctive pore structures. The WO3 raw powder was subjected to ball milling for 5 h to eliminate large agglomerates and achieve a uniform particle size distribution. The sintered bodies exhibited macroscopic pores that were aligned parallel to the direction of freeze-casting. |
