Abstract：

A　wave-absorbing　material　of　Ni-Zn　ferrite　was　prepared　by　a　citric　acid　sol-gel　method　using　diatomite　as　a　matrix.　The　crystal　structure,　surface　morphology,　density　and　electromagnetic　parameters　of　wave-absorbing　material　were　investigated　by　X-ray　diffraction,　infrared　spectroscopy,　scanning　electron　microscopy,　density　analysis　and　radio-frequency　impedance　spectrum　analysis,　respectively.　The　NixZn1-xFe2O4　ferrite　with　a　spinel　structure　is　coated　on　the　surface　of　diatomite,　and　the　apparent　density　of　the　composite　is　in　the　range　of　3.2　to　3.8　g/cm3.　The　electromagnetic　loss　tangent　value　of　diatomite/Ni0.5Zn0.5Fe2O4　composite　ranges　from　0.05　to　0.30.　after　adding　diatomite/Ni0.5Zn0.5Fe2O4　of　15%　(in　mass　fraction)　into　gypsum,　giving　the　maximum　reflectivity　of　the　gypsum　ware　of　-6.12　dB.　©　2016,　Editorial　Department　of　Journal　of　the　Chinese　Ceramic　Society.　All　right　reserved.
