Zinc Oxide

Zinc Oxide is used in many applications due to its variety of functions. Recent developments have expanded the market, such as heat dissipation, transparent conductive layer for solar cell and flat panel display replacing ITO, LED, transparent transistor, thermoelectric conversion and more. We have been researching and developing as a total solution provider/ manufacturer for variety of Zinc Oxide. Still, the tire and rubber industry is the major user of Zinc Oxide. In addition to the quality and cost, we promise to supply the necessary quantity as a leading manufacturer in Asia from our Japan, China, Thailand factory.

Electro-conductive Zinc Oxide

Electrically conductive ZnO powder is a n-type semiconductor doped with different elements. "23-K" is used as antistatic paints for semiconductor factory and applied to control the conductivity of rubber by mixed in rubber products.
types of inorganic, light colored and electrically conductive material are limited, but ZnO has excellent stability and high transparency, so they have started to be applied for many fields. "Pazet" exhibits many functions, UV block, IR block by electro-conductivity and anti-bacteria as Ultra fine Zinc Oxide. Doping metal, doping concentration and particle size can be optimized per customer requirement.

Thin film-forming materials

Zinc Oxide composition for TCO/Semiconductor

We are in a major position to supply ZnO as deposition material, powder types for sputtering targets and tablet types for ion-plating to make TCO transparent conductive films and potical control of doping concentration and particle size.

Zinc Oxide Tablets “ SKY-Z ”

Zinc Oxide Tablets “ SKY-Z ”

Sky-Z series is the ZnO (doped/un-doped) vapor deposition material for the ion-plating method to produce transparent conductive films.
Our Sky-Z has great stability due its splash less architecture.

  • Characteristic of GZO film

Vapor deposition materials replace ITO

ITO is relatively expensive, due to its resource limitation in earth. Most of the rare metals in the world reside in certain countries, which is not suitable for security reasons. Unlike indium, zinc is widely available for commercial use without the risk of shortage

  • Surface resistivity as a function of film thickness

Zinc oxide fine

Nano-particle Zinc Oxide

This Zinc Oxide consists of Nano meter size particles. It has high transparency and protects UV, so it is used for a sunscreen or a UV shielding agent. Though ZnO is friendly for a human body and environment, 100nm size ZnO is also available for the consideration of Nano particle effects to humans.
