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.

Applications

Ceramic capacitors for smartphones, piezoelectric elements of gyroscopes in car navigation systems and video game consoles, optical glass for the lenses of single-lens reflex cameras, films for LCD, and more
