1：Experimental Design and Method Selection:

The study involved cold sintering of ceramic-ceramic composites at 120°C to achieve densification without high-temperature reactions. Theoretical models included finite element modeling to simulate microstructure and electrical properties.

2：Sample Selection and Data Sources:

Composites with varying proportions of Li2MoO4 (LMO) and BaFe12O19 (BF12) (x from 0.00 to 0.15) were synthesized. Powders were mixed using ball milling and densified under pressure.

3：00 to 15) were synthesized. Powders were mixed using ball milling and densified under pressure. List of Experimental Equipment and Materials:

3. List of Experimental Equipment and Materials: Equipment included a variable speed ball mill, die for pressing, furnace for drying, Bruker D2 Phaser X-ray diffractometer, JEOL Inspect F SEM with EDS, EM420 TEM, JEOLR005 HRTEM, GATAN PIPS II ion polishing system, vector network analyzer, waveguide for permeability measurements, and E4980A Precision LCR Meter for impedance spectroscopy. Materials were LMO and BF12 powders with specified grain sizes.

4：Experimental Procedures and Operational Workflow:

Powders were mixed, sieved, wetted with water, pressed in dies at 120°C and 55-70 MPa for 10-40 minutes, dried at 120°C for 24 hours. Structural characterization via XRD, SEM, TEM; electrical characterization via microwave resonance and impedance spectroscopy.

5：Data Analysis Methods:

Data analyzed using finite element modeling (ElCer package), series mixing model for permittivity, and Arrhenius plots for conductivity.
