Functions and Properties for Pioneering the Future
Our unique technologies maximize the potential of zirconium’s
diverse properties and functions and allows us to respond,
as a dedicated zirconium manufacturer, to the wide-ranging needs of our customers.
Solid, yet permeable to oxygen ions
Ionic conductivity
While zirconium ceramics are solids, they exhibit the peculiar property of being permeable to oxygen ions.
Major applications
Fuel cells
Oxygen sensors
Product names
Resistant to heat and chemicals
Heat resistance
The melting point of zirconium oxide is quite high—around 2,700 ℃. Its volume remains virtually unchanged, even at high temperatures. It also exhibits excellent corrosion resistance.
Major applications
Continuous casting nozzles
Refractory bricks
Refractory crucibles
Product names
Diamond-like clarity
Optical properties
Zirconium oxide is colorless, absorbs no visible light, and has a high refractive index, making it an ideal material for adjusting the refractivity. It also exhibits superior abrasion resistance.
Major applications
Anti-refractive (AR) coatings for displays
Hard coatings for eyeglass lenses
Film for adjusting the refractivity of camera lenses

A ceramic material with high toughness
Strength, Toughness
When a force generates microcracks in zirconium ceramics, the force exerted on the areas surrounding the cracks modifies the crystal structure; the resulting volume expansion enhances the strength of the material. Specific to zirconium ceramics, this property has earned them a reputation as high-strength ceramic materials, but with metal-like properties featuring the flexibility of a fishing rod, making them resistant to breaking.
Major applications
Housewares cutting tools (kitchen knives, scissors)
Industrial cutting tools (paper processing machinery, textile machinery)
Product names
A unique, exquisite appearance
Aesthetic use
The gloss and color of zirconium ceramics gives them a high-quality texture that can’t be achieved with other materials and their beauty is kept almost permanently due to their resistance to aging deterioration.
Major applications
Decorations for clocks
Smartphone casing
Product names
Resistant to both acids and alkalis
Chemical resistance
Zirconium ceramics scarcely react with either acids or alkalis. No elution will occur, even under the most severe corrosive environments, like those encountered in the chemical industry.
The ultimate co-star
Supporting catalytic performance
Exhibiting the properties of both an acid and a base, zirconium oxide is an amphoteric oxide. One or the other of these properties may be enhanced depending on the elements added. Zirconium oxides are used to promote the effects of the main catalyst to achieve specific results. For example, cerium-zirconium composite oxides offer enhanced oxygen absorption/release performance compared to cerium oxide, making them the preferred co-catalysts for automobile catalysts.
Major applications
Automotive exhaust gas purification catalysts
Catalysts for chemical synthesis

A bridge between organic and inorganic materials
Cross linking agent
Zirconium exhibits high affinity to oxygen and tends to bond with carboxyl and hydroxyl groups. It can be used to form cross linking bonds with organic compounds that have these groups to add properties like low tackiness or water resistance.
Major applications
Paints
Binders
Cross linking agents for water-soluble polymers in papermaking
Product names
Converting power into electricity and electricity into power
Piezoelectric effect
A material called PZT (lead zirconate titanate) ceramics produces an electric charge when compressed and deforms when an electric field is applied.
Major applications
Actuators
Spark plugs
Housing for earphones/speakers
