Study on Properties of Slurry for Making Zirconia Fiber

Abstract:

Article Preview

Zirconia fibers have recently become a research hotspot for their superior physical and chemical properties. In this paper, zirconia slurry was prepared by inorganic salt solution added with zirconia powders, the effect of content of PVA, PEG and zirconia powder solid content of the slurry on properties of slurry was studied. Research shows that: the content of PEG as a dispersing agent was 5wt.%, The dispersibility of zirconia powder and stability of slurry got the best, but slurry viscosity was correspondingly higher. Solid content of zirconia powder had an important impact on the rheological properties of slurry, when zirconia solid content was less than 30%, the slurry showed as a pseudoplastic fluid, whereas the zirconia solid content of slurry became 40% and 50% it exhibited plastic fluid characteristics. Solid content of slurry was 50wt.%, the stability of slurry got the best.
