Lava Frame (3M ESPE) is a tetragonal zirconia polycrystal
partially stabilized with 3mol-% yttria.
When the whole material is constituted by transformable t-zirconia grains it is called Tetragonal zirconia polycrystals
Dominguez-Rodriguez, "High temperature creep behaviour of 4 mol% yttria tetragonal zirconia polycrystals
(4-YTZP) with grain sizes between 0.38 and 1.15 [micro]m," Journal of the European Ceramic Society, vol.
As an example, zirconia ceramics such as 3Y-TZP (3 mol % Yttria-stabilized Tetragonal Zirconia Polycrystals
) offer unsurpassed mechanical properties but are also the most opaque of all-ceramic materials currently available .
CeraPure YTZP (yttria-stabilized tetragonal zirconia polycrystals
) provides excellent chemical resistance in chemically corrosive environments, and its flexural strength is nearly double that of traditional ZTA, data from CoorsTek indicates.
