Synthetic process of rod zirconium boride powder
The invention provides a synthetic process of rod zirconium boride powder and belongs to the technical field of powdery materials. The synthetic process is characterized by including 1, preparing carbon powder: curing thermosetting phenol resin at 80-120 DEG C, calcining the resin at 200-1500 DEG C in an argon atmosphere at a temperature rise rate of 8-12 DEG C/min, and holding the temperature for 10-30 min to generate carbon powder through splitting; 2, mixing raw materials: crushing the carbon powder, and mixing zirconium tetrachloride, boric acid and the carbon powder according to a molar ratio of 1:2:5; 3, performing sintering: sintering mixed powder at 1650-1750 DEG C in the argon atmosphere, and holding the temperature for 0.5-2 h t to obtain the rod zirconium boride powder. The synthetic process has the advantages that sintering temperature is low, the process is simple, operating is safe, the cost is low, the process is easy to popularize, and the prepared rod zirconium boride powder has good dispersity and a length-diameter ratio increased by 4 times.
