Ultra-high temperature ceramic matrix composites were firstly made by eutectic method. The composites were made from ZrB₂ and flake graphite, ZrB₂, TaB₂, SiC and flake graphite,or ZrB₂, MoSi₂and flake graphite, respectively. Results shows that different phases distribute uniformly in these composites, and the graphite phases in the composites were highly ordered. The d₀₀₂ values of the graphite in the composites were 0.335 4, 0.335 9 and 0.337 7 nm, and the L_c values were 63.4, 51.5 and 68.7 nm, respectively. Boron had already doped into the carbon net, as indicated by the Raman analysis, and some amount of pores existed in the composites. Also, thermal conductivity coefficient of the composites were not very high. Eutectic method could be a promising method for making ultra-high temperature ceramic matrix composites.
