Application for zirconia yttria stabilized:
1. Zirconia is one kind which widely used
in ceramic material, it has three kinds of structures of different phases,
namely monoclinic, tetragonal and cubic phases, different phase content have a
great impact to zirconia ceramic materials. Currently, the common is the yttria
stabilized zirconia material.
2. With the increase of the molar fraction
of yttria, when the yttria content is 3%, the zirconia ceramics bending
strength increases rapidly to obtain the maximum strength, increase the content
of yttrium oxide , the intensity value is no longer increased, and gradually
turn reduced.
3. Content of yttria affect the tetragonal
zirconia content and stability, and when the content of yttrium oxide is
larger, it generating some parts of cubic zirconia, when the content of
tetragonal zirconia is low, the intensity decreased.
4. By adding monoclinic zirconia, zirconia
change Y2O3 molar fraction of the ceramic material, at a lower raw material
cost while improving the mechanical properties of zirconia ceramics containing
yttria, so that the anti-bending strength, hardness, density, With the
ascension of the whole performance such as zirconia ceramics industrial
production provided the conditions.
