Description
Summary:A sol-gel processing was used to low temperature. Orthorhombic synthesize （Cao.61,Ndo.26）TiO3 （CNT） perovskite structure phase with a smal nanoparticles doped with Li-Cu-B at amount of Li3BO3 secondary phase was formed by calcining the xerogels at 300℃, and monodisperse CNT nano-powders with the grain size of 10-15 nm could be obtained. By using these nanocrystalline CNT powders, dense CNT ceramics could be achieved at the low sintering temperature of 1100℃ due to the effect of the small size nanoparticles and liquid phase Li3BO3. And the dielectric properties with dielectric constant （εr= 89.52）, quality value factors with frequency （Q×f=17148 GHz） and the temperature coefficient of resonant frequency （τf） value of ＋239×10^-6/℃ were achieved.
