In MLCC (Multilayer Ceramic Capacitors) and electronic ceramics, impurity control is critical.

Trace elements such as:

· Iron (Fe)

· Sodium (Na)

· Calcium (Ca)

· Silicon (Si)

can significantly affect:

· Dielectric constant

· Crystal structure stability

· Electrical performance

· Long-term reliability

Therefore, high purity barium hydroxide is required to ensure stable BaTiO₃ ceramic performance.
