The fascinating world of Tosoh Zirconia
. . . where value and potential are limited only by oneÕs imagination
The unlimited possibilities for ZirconiaZirconia is a unique advanced ceramic – a chemical compound having the formula ZrO2.
Products manufactured from Tosoh’s yttria-stabilized zirconia (YSZ) powder exhibit
superior mechanical properties such as high strength and flexibility. As a technological
breakthrough, YSZ surpasses the strength limitations of traditional fine ceramics. Heat
insulating properties and oxygen-ion conductivity indicate zirconia has potential for use in a
wide variety of applications – everything from telecommunications to the new energy of the
future and environmental products.
Market share – proof of qualityTosoh is a pioneer in the development of YSZ and has become a major supplier to the
world. Earning a solid reputation for consistent high purity and quality that customers can
depend on, Tosoh continues to focus resources in R&D and customer services for the
ultimate evolution of Zirconia.
Grinding Media
SUPERIOR STRENGTH and DURABILITY,Tosoh’s zirconia grinding media is primarilyspherical and comes in a variety of sizes from 0.03mm to 25 mm. It is used to process materials fornot only machines and industrial parts, but alsoplays a vital role in the production of materials thatcomprise the micron-thin layers of electronics for mobile phones, as well as the processing of pigments in printing inks.
Indispensable for fiber-optic networks (ferrules, sleeves)
The information age of today and tomorrow is being built on global fiber-opticnetworks. Zirconia is an indispensable material used in the connectors withinthose networks.
STRONG, FLEXIBLE, and EASY to PROCESS, zirconia is rapidlybecoming the world standard for fiber-optic connectors – providing themaximum amount of data transmission with minimal loss.
Environmentally friendly and energy conservation
OXYGEN-ION CONDUCTIVITY is a UNIQUE QUALITYof zirconia.This fascinating characteristic makes zirconia useful inenvironmental applications for solid oxide fuel cells, which generatepollution-free electricity, as well as oxygen and NOx sensors used inthe automotive field.
Dental Materials
Combining STRENGTH and NATURAL BEAUTYReplicating the natural look and feel of real teethwithout compromising strength, Zirconia is nowgaining attention as a new dental material.
Mechanical Parts
Zirconia first appeared under the name “Ceramic Steel”.
In addition to strength, zirconia is RESISTANT to RUST,
CORROSION, and CHEMICAL REACTIONS, andtherefore is used in a variety of machines and other
industrial equipment. 10X standard ceramics,
and 100X MORE HEAT INSULATION THAN IRON,zirconia excels in heat shielding applications.
Providing value in daily life
INCREDIBLY DURABLE and SOFT to the TOUCH, zirconia is used inconsumer goods, such as luxury watches. For professional chefs, zirconiaknives don’t rust and stay extremely sharp while resisting stains and odors.
The future of ZIRCONIA IS JUST BEGINNING…
Basic Grades
◆TZ-3Y-E
Partially-stabilized zirconia powder with uniform dispersion of
3 mol % yttria. TZ-3Y-E exhibits superior sintering properties
and higher aging resistance at a lower sintering temperature
of 1300oC. Sintered bodies produced with TZ-3Y-E show a
fine crystal grain structure resulting in greater improvements
in strength, fracture toughness, as well as resistance to wear
and aging. TZ-3Y-E has numerous applications such as
materials for industrial parts and everyday products.
◆TZ-4Y TZ-6Y TZ-8Y TZ-10Y
Fully stabilized zirconia powder with uniform dispersion of
4~10 mol % yttria. Sintered bodies produced from these
powders exhibit oxygen-ion conductivity and heat insulating.
These grades have proven to be suitable for use in oxygen
sensor applications, electrolytes in solid oxide fuel cells,
materials for heat insulation, and many others.
○● Tosoh Zirconia Powder Series
Easy Moldability Grades “S”
"S" grades have a smaller surface area that contributes to
a smooth flow for the compound or slurry during injection
molding, tape casting, and other molding methods.
Therefore, "S" grades are highly recommended for producing
large parts with a mechanical press or CIP.
Binder Grades “B”
Tosoh's binder added grades are perfect for mechanical
pressing and CIP. "B" grades can be used "as is," thereby
eliminating the binder addition and spray drying steps in
customers' processes.
ATZ Grades “A”
“A” grades contain uniformly dispersed 3 mol % yttria, 20
wt% alumina, and exhibit extremely high mechanical
strength after HIPing. This grade is most commonly used to
produce industrial parts used in high strength, high wear
resistance applications.
Color Zirconia
Tosoh's color zirconia shows a deep tone that emulates
jewels. Also it can be used for optical anti-reflection and
other mechanical parts.
Tosoh also supplies a high purity, non-stabilized zirconia powder, TZ-0.For the development of custom powders, please contact the nearestTosoh sales office.
Using the latest hydrolysis processes and nano-technologies, Tosoh produced the TZ Series
of zirconia powders. Through complete control over materials and production processes,
Tosoh can maintain consistent high purity and quality. The TZ Series, the ultimate zirconia
powder, delivers added value and product improvements for the customer.

fracture toughness and wear resistance. It is produced by Nikkato Corporation, one of Japan’s leading
ceramic manufacturers and a pioneer in the development of strength-enhanced zirconia ceramics. Starting
with the raw materials, YTZ® Grinding Media has been researched and examined from all possible
perspectives to produce superior quality.
Ceramic Media Properties
Due to the unique properties of ceramics, YTZ® Grinding
Media is resistant to rust and corrosion, and thus compatible
with water-based processing.
Additionally, YTZ® Grinding Media, produced from yttria-
stabilized zirconia “YSZ” powder, exhibits superior grinding
efficiency because of higher density, and has superior wear
resistance due to high crushing strength and fracture
durability.
YTZ® Qualities
YSZ powder used for materials is produced through the
latest hydrolysis process, known as the “Tosoh process” and
achieves consistent high quality.
YTZ® Grinding Media consists of high purity YSZ without any
kind of heavy metals. Moreover YTZ® Grinding Media
exhibits high wear resistance, which combined with its
smooth surface minimizes product contamination from both
media wear and mill parts.

The test data above is a result of wet milling BaTiO3 powder with a starting surface area of 1.8m2/g. Grinding wasconducted with several types of media in a vertical sand mill over a set period of time. As can be seen, YTZ® hassuperior grinding efficiency with the highest wear resistance. The highest surface area of the ground material wasachieved with YTZ® over the same period of time under identical conditions. This is a clear indication of the highmilling efficiency that YTZ® provides.
