文摘
- •
Self-composite property-tunable LaTiNbO6 ceramics were obtained by post-annealing.
- •
Near-zero τf was yielded in the sample with one-hour annealing.
- •
Orthorhombic LaTiNbO6 phase with a high εr and a positive τf was first reported.
- •
A special microstructure evolution was disclosed by a novel self-healing process.
- •
A novel concept of ‘self composite’ was proposed in microwave dielectric ceramics.
