Product Description
Product Introduction
Barium Titanate (BaTiO₃) nanoparticles are a cutting-edge ceramic material widely valued for their exceptional dielectric, ferroelectric, and piezoelectric properties at the nanoscale. With a particle size typically below 100 nm, BaTiO₃ nanoparticles exhibit enhanced surface area, faster sintering behavior, and improved electrical characteristics compared to their micron-sized counterparts.
These nanoparticles are extensively used in advanced electronic and energy storage applications such as multilayer ceramic capacitors (MLCCs), embedded passive components, high-k dielectric films, lead-free piezoelectric devices, and electro-optic systems. The high dielectric constant and tunable Curie temperature make them ideal for next-generation microelectronics and miniaturized devices where size, performance, and reliability are critical.
Our BaTiO₃ nanoparticles are synthesized with strict control over phase purity, stoichiometry, and morphology to ensure batch-to-batch consistency and optimal performance. They are available in unmodified or surface-treated forms, enabling excellent dispersion in various solvents, inks, or polymer matrices for composite fabrication and thin-film
