摘要: Uniform densification of relatively thick (~7 mm) consolidated boron carbide plates at low temperatures (e.g. 1800°C) and facture toughness are two the primary challenges for further development applications. This work reports that these can be overcome simultaneously by adding 5 wt% alumina as a sintering aid. Nearly fully dense (97%), fine grained (B4C) samples were produced using spark plasma 1700°C above in B4C-5 wt% Al2O3 system. The matrix reacted to form an Al5O6BO3 (a mullite-like phase) during sintering. phase facilitated uniform via liquid secondary is dispersed throughout intergranular pores, providing obstacles crack propagation resulting tougher ceramics.
