ZrB_2-SiC eutectic powders with a lamellar texture was prepared, and then the powders were sintered without sintering additive by spark plasma sintering. Dense ZrB_2-SiC eutectic composites with the lamellar texture were successfully fabricated. The ZrB_2-SiC eutectic composites had similar mechanical properties and oxidation resistance to typical ZrB_2-SiC composites.

制备了具有片层结构的ZrB_2-SiC共晶粉末，在不添加烧结添加剂的情况下，采用火花等离子烧结技术对其进行烧结。成功制备了具有片层织构的致密ZrB_2-SiC共晶复合材料。ZrB_2-SiC共晶复合材料具有与典型ZrB_2-SiC复合材料相似的力学性能和抗氧化性能。
