Zirconium oxide

Features

Our zirconium oxide is extremely fine, with primary particles that are around 20 nanometers in diameter, and is high in purity.
It is used as materials for electronic parts that support IT devices, and contributes to their high functionality.

Uses

Ceramic capacitors for smartphones, piezoelectric elements for car navigation systems or gyro sensors for gaming devices, and optical glass for lenses in single-lens reflex cameras
