Crystallization of the relaxed melt at ambient pressure leads to formation of tetragonal Form II crystals which also has been classified as a mesophase [13].
In 1959 it was discovered that as the material cools, it changes from a metal to a semiconductor while its atoms reorganize themselves from a tetragonal to monoclinic crystal structure.

4, 2014 /PRNewswire/ -- In a new white paper, Superior Technical Ceramics (STC) has outlined the effects moisture, hydrogen and water can have on Yttria-stabilized Tetragonal Zirconia Polycrystal (YTZP) and discusses alternatives such as Ceria Stabilized Zirconia (CSZ) and Magnesia Stabilized Zirconia (MSZ).
Since non-silica based Yttria partially stabilized tetragonal zirconia (Y-TZP) are resistant to etching [3], other techniques such as air-abrasion, silanization and laser irradiation are used to increase the roughness of zirconia surface [4].
Zirconia has three different structures: monoclinic, tetragonal and cubic.
Zirconia is also known to gradually weaken over time as the crystal structure changes from a tetragonal phase to a monoclinic one when exposed to hydrothermal condition.
b) tetragonal or square numbers such as 1, 4, 9, 16, 25, etc.
The lobes, which are future spore domains, are in tetrahedral arrangement, although they may appear tetragonal due to flattening during processing.
The Soilon tea bag filter (with/without string and tag) is available in two shapes, tetrahedral bag like pyramid and conventional tetragonal bag.
