Barium Titanate
Applications
Used in multilayer ceramic capacitors (MLCCs), thermistors, piezoelectric sensors, and electro-optical devices. It also serves as a component in nonlinear optics and energy storage systems.
Safety & Risks
Chemically stable but may generate fine particulate dust; wear respiratory protection when handling. Avoid contamination with organics or moisture that can affect dielectric behavior.
Packaging
Delivered in 10–25 kg sealed fiber drums or antistatic PE-lined containers. Store dry, cool, and protected from vibration and humidity.
