Manganese cerium doped nickel zinc ferrite nano wave absorbing powder and preparation method thereof
The invention relates to manganese cerium doped nickel zinc ferrite nano wave absorbing powder and a preparation method of the manganese cerium doped nickel zinc ferrite nano wave absorbing powder. According to the manganese cerium doped nickel zinc ferrite nano wave absorbing powder, a proper amount of manganese and cerium are added into nickel zinc ferrite to prepare nano nickel-based ferrite, the widening and matching thickness of a wave absorbing frequency band is reduced, and the wave absorbing powder meets the requirements for high absorption and the wide frequency band. According to the chemometry general formula Mn0.2+2yNi0.5-yZn0.3-yCexFe2-xO4 of the wave absorbing powder, a sol-gel method is adopted, nickel zinc ferrite precursors with different manganese cerium doping amounts are obtained, and the manganese cerium doped nickel zinc ferrite nano wave absorbing powder is obtained after high-temperature calcination. The process is simple, energy consumption is reduced, the wave absorbing powder is good in electromagnetic performance, and broadband absorption on radar waves can be achieved within the frequency band of 2 GHz to 18 GHz.
