NdAlO3-CaTiO3微波介质陶瓷材料的研究
Study on NdAlO3-CaTiO3 microwave dielectric ceramics
摘要
Abstract
To achieve the excellent microwave dielectric properties of NdAIO3-CaTiO3 ceramics, (1-χ)NdA1O3-χCaTiO3 ceramics were prepared by the solid state reaction method. The effects of x value on the property and structure of NdAlO3-CaTiO3 ceramics were studied. The results show that; when x equals to 0.60, 0,65, 0.70, 0.75, 0.80, all the prepared ceramics show a compact structure, few air bubbles and distinct crystal boundary, and the main phase of ali the ceramics is (l-χ)NdAtQ3-χCaTiO3. The density of NdAlOrCaTiO3 ceramics decreases from 4.95 g/cm3 to 4.45 g/cm3 almost linearly with increasing x value, while their particle size increases from 4 urn to 10 μm, relative permittivity ε, increases from 38 to 65, temperature coefficient of resonant frequency τf increases from-9× 10-6 /K to 32×10-6/K, Q ·/fvalue decreases from 38 000 to 29 000.关键词
