Barium titanate foam ceramics loaded with micro/nano silver and preparation method thereof
Disclosed are a micrometer/nanometer silver-loaded barium titanate foam ceramic and a preparation method therefor. An organic additive is used as an auxiliary; deionized water is used as a solvent; nanometer barium titanate is used as a ceramic raw material; and same are mixed and ground so as to form a slurry.
