High-entropy wave-absorbing carbide ceramic powder material as well as preparation method and application thereof
The invention provides a high-entropy wave-absorbing carbide ceramic powder material as well as a preparation method and application thereof. The ceramic powder material is prepared from the followingraw materials in mole ratio: 0-5mol% of titanium dioxide, 0-5mol% of zirconium dioxide, 0-5mol% of hafnium dioxide, 0-2.5 mol% of niobium pentoxide, 0-2.5 mol% of tantalum pentoxide, 0-2.5 mol% of vanadium pentoxide and the balance of carbon black, the dosage of any more than five transition metal oxides is not 0. The preparation method comprises the following steps of: selecting five or more ofthe transition metal oxides; mixing the transition metal oxides with carbon black in the presence of a mixed medium to obtain uniformly mixed slurry; drying the slurry, sieving the slurry to obtain mixed powder, and calcining the powder to obtain the carbide ceramic powder material. The high-entropy ceramic powder material disclosed by the invention has the characteristics of high purity, good wave-absorbing performance and wide absorption frequency band, and has an excellent application prospect in the field of wave-absorbing materials.
