研究目的
Investigating the structure-property relationship of co-substituted NdNbO4 ceramics to achieve optimal microwave dielectric properties.
研究成果
The co-substitution of (A1-xMox)5+ for Nb5+ in NdNbO4 ceramics leads to improved microwave dielectric properties, with the optimal properties achieved for NdNb0.97(Si0.5Mo0.5)0.03O4. The study highlights the importance of bond characteristics and structure stability in determining dielectric properties.
研究不足
The study focuses on the intrinsic loss and does not extensively discuss the extrinsic factors affecting the Q×f values. The range of co-substitution ions is limited to (Mg2+1/4Mo6+3/4)5+, (Al3+1/3Mo6+2/3)5+, (Si4+1/2Mo6+1/2)5+, (Zr4+1/2Mo6+1/2)5+.
