What is Barium Titanate？

Barium Titanate is a ceramic compound appearing as a white crystalline powder with a perovskite crystal structure. It is insoluble in water and organic solvents but soluble in concentrated acids. The material exhibits ferroelectric, piezoelectric, and dielectric properties, making it a key functional material in electronic applications. It is known for its high dielectric constant and Curie temperature (~120°C).

Safety Profile:

Barium Titanate may be harmful if swallowed or inhaled. Causes eye and skin irritation. Use appropriate personal protective equipment including dust mask, safety glasses, and gloves when handling. Avoid breathing dust. The substance contains barium which is toxic to aquatic life. For detailed safety information, always consult the full Safety Data Sheet (SDS).

Storage Requirements:

Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly closed and sealed. Maintain storage temperature below 30°C. Relative humidity below 60% recommended. Store away from strong acids.

Transport & Packaging:

Barium Titanate is packaged in paper-plastic composite bags with inner polyethylene liner (25 kg net weight per bag). Transport as hazardous material due to barium content according to applicable regulations. Ensure containers are properly sealed and protected from moisture during transportation. Store away from incompatible materials.
