Tape Casting for Multilayer Piezoelectric Ceramics: Key Technologies for Ultra-Thin Green Tape Fabrication

2025-11-27

Tape casting is the core process enabling thin-film and large-area production of multilayer piezoelectric ceramics. It supports the preparation of uniform ceramic green tapes with a thickness of 5–50μm and sizes >100 mm×100 mm, effectively overcoming the technical limitations of dry pressing, which tends to crack when thinning below 50 μm and deform when the area exceeds 50 mm×50 mm.
