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.

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.
