Product Description
Product Introduction
Barium Titanate (BaTiO₃) powder is a high-performance ceramic material widely used in the electronics industry due to its excellent dielectric, ferroelectric, and piezoelectric properties. As a key component in a range of electronic and electroceramic devices, BaTiO₃ serves as the foundational material for manufacturing multilayer ceramic capacitors (MLCCs), thermistors, varistors, piezoelectric actuators, and electro-optic devices.
Our Barium Titanate powder is engineered with high purity, uniform particle size distribution, and excellent thermal stability. It is available in submicron and micron grades to suit various processing requirements, including tape casting, dry pressing, extrusion, and injection molding. The consistent morphology ensures superior sintering behavior, high densification, and reliable electrical performance in the final ceramic components.
This powder can be tailored through controlled doping or surface treatments to meet specific functional requirements such as Curie temperature adjustment, grain growth control, and enhanced dielectric performance. It is ideal for applications requiring high permittivity, low leakage current, and long-term reliability.
