Abstract

This study investigates the characteristics and fabrication techniques of
laminated ceramic composites, focusing on various glass-ceramic systems,
including alumina, BaTiO3/Al2O3, and LiO2‐ZrO2‐SiO2‐Al2O3 (LZSA). The
inherent brittleness of ceramics, attributed to surface flaws and their limited
toughness, necessitates the development of layered structures to enhance
mechanical reliability. Layered ceramics demonstrate improved fracture
toughness, crucial for applications in aerospace, biomedicine, and military
armor. Techniques such as tape casting, electrophoretic deposition, and
advanced sintering methods, including hot press, spark plasma, and cold
sintering, are employed to fabricate and strengthen these materials.This
research also explores the integration of bionic principles into ceramic
lamination, revealing improvements in toughness and defect resistance.
Specifically, the development of BaTiO3/Al2O3/ZrO2 laminates through
electrophoretic deposition demonstrates potential in energy harvesting
applications by utilizing residual stress and the piezoelectric effect. Additionally,
glass infiltration techniques, using commercial glass systems such as MgO-
B2O3-SiO2 and PbO-B2O3-SiO2, are optimized to bond different ceramic layers
effectively, reducing defects and enhancing structural integrity. The study further
examines the thermal, mechanical, and dielectric properties of LZSA glass-
ceramic composites, modified with ZrSiO4 and nano-Al2O3 to control the
thermal expansion coefficient (TEC) and improve microstructural properties. The
findings present a comprehensive understanding of ceramic lamination
techniques, highlighting the significance of sintering processes and material
composition in enhancing the performance and applicability of ceramic
laminates across various industries.
