As a true breakthrough material in the electronic ceramics industry for more than half a century, Barium Titanate (BaTiO3) has found widespread applications in multi-layer ceramic capacitors (MLCCs), embedded decoupling capacitors (EDC), PTC thermistors, ceramic filters, and other piezoelectric & ferroelectric components

  • Dielectric Ceramics: used for capacitors; Capacitor energy storage devices are used in electric vehicles.
  • Piezoelectric Materials: used for microphones and transducers.
  • Also used as Single Crystals; single crystals of Barium Titanate exhibit negative temperature co-efficient of resistivity (NTCR) properties.
