 IIIIIIIVV    
I:mol % of yttria, where "3Y" would be 3 mol% Y2O3    
II:"S" for easy moldability grades    
III:ATZ grades, where "20A" would be 20 wt% alumina    
IV:binder grades, where "B" would be binder 3% grades, and "BC" would be binder 5% grades    
V: "E" for easy sintering grades    

 

Basic Grades
TZ-3Y-E, TZ-3YB-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 including materials for industrial parts and everyday products.

S Grades
TZ-3YS-E, TZ-3YSB-E, TZ-3YSB-C
S grades have a smaller surface area that contributes to a smooth flow for the compound or slurry in injection molding, tape casting, and other molding methods. S grades are highly recommended for producing large parts by a mechanical press or CIP.

ATZ Grades
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 in high strength, high water resistance applications.
