Combustion synthesis method of multi-component transition metal boride ceramic powder
The invention discloses a combustion synthesis method of multi-component transition metal boride ceramic powder, relates to the field of ultrahigh-temperature ceramic materials, and aims to solve the problems of low purity and low production efficiency of the index multi-component transition metal boride ceramic powder in the conventional method. The method comprises the following steps: 1, preparing transition metal oxide solid solution powder from transition metal powder and transition metal oxide powder through combustion synthesis; 2, adding boron oxide and magnesium powder into the transition metal oxide solid solution powder, and uniformly mixing; 3, putting the mixed material into a closed reaction container, igniting, and carrying out a self-propagating magnesiothermic reduction reaction; and 4, cooling, taking out a reaction product, and carrying out acid pickling, suction filtration, washing and drying to obtain the multi-component transition metal boride ceramic powder. According to the method, the production time is greatly shortened, and the production efficiency can be improved. The prepared multi-component transition metal boride ceramic powder has high purity and high solid solution degree. The method is used for preparing the multi-component transition metal boride ceramic powder.
