Main uses: Barium titanate is used in almost all ultrasonic instruments; it is employed in the formulation of various electronic components such as electronic ceramics, PTC thermistors, and capacitors. High-purity ultrafine barium titanate powder is primarily used in the manufacturing of dielectric ceramics and sensitive ceramics. In the electronics industry, barium titanate ceramics are a typical ferroelectric material and an important PTC (positive temperature coefficient) material.

Its crystals possess a high dielectric constant, stable electrical constant, and thermally variable parameters, making them suitable as materials for manufacturing components such as nonlinear elements, dielectric amplifiers, memory elements for electronic computers, micro-capacitors, and ultrasonic generators. Barium titanate also exhibits piezoelectric properties for electromechanical conversion. It can be used as a material for phonograph heads, groundwater detection devices, underwater detectors, and more. The company has an annual output of 10,000 tons.
