Micronized zirconia and method for production thereof. |
摘要 |
<p>A method for the production of micronized zirconia by the addition of an alkali to an aqueous solution of a zirconium salt or to a mixed aqueous solution of said zirconium salt and a stabilizer such as yttrium, calcium, and magnesium compounds, which method comprises carrying out the reaction for formulation of a hydroxide by the addition of the alkali continuously in a flow type reaction system while keeping the p" of said reaction system at a fixed level, separating the hydroxide produced consequently by the reaction, and drying and calcining the separated hydroxide, and a zirconia-containing micronized particle which contains such stabilizer and has an average particle diameter of not more than 0.02 µm.</p> |
