Abstract: | Nanosized molybdenum boride and carbide were synthesized from MoO3, KBH4, and CCl4 by thermo-synthesis method at lower temperature. The relative content of Mo, Mo2C, and molybdenum boride in the product was decided by the molar ratio between MoO3, KBH4, and CCl4. Increasing the molar ratio of CCl4 to MoO3 was favorable to the production of Mo2C. Increasing the molar ratio of KBH4 to MoO3 was favorable to the production of molybdenum boride. By carefully adjusting the reaction conditions and annealing in Ar at 900°C, a single phase of MoB could be obtained. |
