The present invention relates to a kind of preparation method of the ternary compound base flexible, porous ceramic composite of ternary boride enhancing, by Mo 2 NiB 2 Powder, Ti 3 MC 2 Powder and carbonate powder press following atomic percent at.% batch mixings, Mo 2 NiB 2 ：15% 25%, Ti 3 MC 2 ：50% 60%, carbonate：15%‑35%；The material prepared is put into ball mill to be mixed, milling atmosphere is vacuum or inert gas shielding, ratio of grinding media to material 1:1‑3:1, when Ball-milling Time 68 is small；The powder mixed is suppressed using cold-press moulding equipment hydraulic press, pressing pressure is controlled in 350 400MPa；Compressing cold pressing base is put into vacuum drying oven and carries out reaction-sintered, reaction temperature is 1,200 1400 DEG C, and the reaction-sintered time is 120 180 minutes, and vacuum degree control is 10 ‑3 ‑10 ‑2 Pa, furnace cooling after the completion of reaction. |
