Titanium dioxide-based giant dielectric ceramic material and preparation method thereof
The invention discloses a method for preparing a titanium dioxide-based giant dielectric ceramic material by adopting a solid-phase sintering method. The general formula of the titanium dioxide-based giant dielectric ceramic material is (Tm0.5Nb0.5)x(Ti<1-y>By)<1-x>O2 (x is equal to 0 to 0.1, y is equal to 0 to 0.1), and B represents Zr, Sn, Hf or Ge. The method is a solid-phase sintering method, the method is simple, the repeatability is good, the yield is high, the frequency stability of the obtained titanium dioxide-based giant dielectric ceramic material within the range of 20 Hz-1 MHz is good, the dielectric constant is 104-105, and the insulation resistivity is 108-1013 [omega]cm. In addition, the material has excellent temperature stability at the temperature ranging from -150 DEG C to 260 DEG C. The titanium dioxide-based giant dielectric ceramic material has practical application value in various electronic devices such as capacitors and dynamic memories.
