Description
Technical field：
The present invention relates to nano material production field, is specifically exactly a kind of spherical yttrium stable zirconium oxide nanometer of size uniform
Raw powder's production technology.
Background technology：
Zirconium oxide（ZrO2）It is a kind of very important structural and functional material, wear-resistant with chemical stability, heat conduction system
The characteristics such as low, the high temperature resistant of number, corrosion resistance, heat stability and impact resistance, are fire resistant covering material, high-temperature structural material, life
The important source material of thing material and electronic material, is widely applied in fields such as energy, material, electronics and environment.
Pure ZrO at room temperature2For white crystal, fusing point is 2680 DEG C, and boiling point is 4275 DEG C.Zirconium dioxide is more than one
Crystal system, can be divided into three kinds of crystal formations：Monoclinic system（Monoclinic, m-ZrO2）, tetragonal crystal system（Tetragonal, t-ZrO2）
And cubic system（Cubic, c-ZrO2）.Monoclinic phase is stable phase under room temperature, and Tetragonal and Emission in Cubic are metastable phases.These are brilliant
Reversible phase in version can occur between type, while causing great bulk effect, be such as heated under the conditions of 1150 DEG C, zirconium dioxide
It is changed into Tetragonal, volume contraction from monoclinic phase；During cooling, the opposite monoclinic phase transformation in four directions should along with about 6% ~ 8% shearing
Become the volumetric expansion with 3% ~ 5%, so as to the material for preparing easily is cracked, or even rupture, therefore without great construction value.
In recent years, by particle ionic radius and valence number and the Zr of adulterating4+Close metal ion, such as Ca2+、Mg2+With
Y3+Deng.When introducing Y in zirconium oxide crystals3+During metal ion, they replace the position of zirconium ion in lattice, in order to ensure grain
The electric neutrality of son can produce oxygen vacancies, and the Lacking oxygen being distributed in around zirconium ion reduces the repulsive force between oxygen oxygen so that match somebody with somebody
Position layer produces larger distortion, so as to promote room temperature condition under Tetragonal or Emission in Cubic zirconium dioxide stablize.
Prepare nanometer Y2O3-ZrO2The method of powder body is more, mainly has：Chemical precipitation method, Emulsions method, collosol and gel
Method and hydro-thermal method etc..The powder body that generally chemical precipitation method is prepared needs high-temperature calcination, and particle bad dispersibility, agglomeration is tight
