Absztrakt (kivonat)
In this work, the microstructure and thermal properties of lithium-niobium-titanium-oxide (Li-Nb-Ti-O) solid-solution ceramics were investigated using the X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and differential scanning calorimetry (DSC) techniques. XRD and SEM analysis confirmed that Li-Nb-Ti-O ceramic sample synthesized by solid-state method reaches the desired composition of so-called Mphase of the Li2O-Nb2O5-TiO2 ternary system (Li6.87Nb2.34Ti5.78O21) that should have excellent microwave dielectric properties. The M-phase was obtained with lower than 1000ºC sintering temperature by doping with MoO3 as flux material, which makes this kind of ceramic material suitable for the low temperature co-fired ceramic (LTCC) technology applications. The heat flow data obtained from DSC measurement were used to calculate the specific heat capacity (Cp) of synthesized Li6.87Nb2.34Ti5.78O21 solid-solution ceramics, which is the property of a material that tells about its stability and functionality.
