Abstract (en)

[origin: WO8300347A1] Titanium diboride graphite composite articles are produced by mixing TiO2, petroleum coke and a binder to form a plastic dispersion. Articles are shaped by molding or extrusion and baked to carbonize the binder to form a baked carbon-TiO2 composite. The article is impregnated with a molten or dispersed boron compound, or with a boron compound mixed with carbon black, then heated to drive TiB2 forming reaction. The article is then further heated to a graphitizing temperature to form a graphite-TiB2 composite useful as a cathode component in a Hall aluminum reduction cell.
