Abstract
With a combination of excellent properties, including extremely high melting temperatures, high hardness, low volatilities, good thermal and electrical conductivities, ZrB2-based ultra high temperature ceramics (UHTCs) become viable candidates for high-temperature structural applications. ZrB2 owns AlB2-type hexagonal structure (P6/mmm) and shows high anisotropy in single-crystal form, platelet ZrB2 grains could be formed in reactive hot pressed ZrB2-MoSi2 at temperature of 1650 C. In present work, textured ZrB2 and ZrB2-MoSi2 ceramics were fabricated via strong magnetic field alignment during slip casting, followed by spark plasma sintering. The results on sintering and microstructure of the received textured ceramics will be reported.
