Abstract:

Electrophoresis is the movement of particles suspended in a liquid under influence of an electric field. Electrophoretic forming of silicon carbide (SiC) requires the simultaneous deposition of SiC and sintering aids such as carbon and boron. The incorporation of the sintering additives was studied in two ways: co-deposition of a boron-containing SiC powder and carbon black, as well as the co-deposition of SiC, boron carbide and carbon black. A high final density after sintering (>95%) was obtained with the two approaches. © 1996 Elsevier Science Limited.
