Titanium oxide (TiO 2 ) and boron carbide (B 4 C) were added to TiB 2 raw powders to prepare porous TiB 2 ceramics by reactive spark plasma sintering, and the gas escape (such as CO and B 2 O 3 ) resulted in higher porosity. X-ray Diffraction results indicated that the reduction reaction was completed after the reactive spark plasma sintering process...
