AI Technical Summary

Technical Problem

Existing technologies make it difficult to directly and continuously prepare high-density, high-sphericity fused zirconia solid spheres. Traditional methods suffer from problems such as long processes, high energy consumption, and limited product performance.

Method used

A consumable electrode is prepared by uniformly mixing zirconia powder with a stabilizer using a titration method. The electrode is then melted and dripped under inert gas protection to form a solid fused zirconia sphere. By controlling the arc current, feed rate, and cooling medium flow rate, a one-step forming process is achieved.

Benefits of technology

It has achieved the production of high-density (≥99.0%) and high sphericity (true sphericity >95%) fused zirconia solid spheres, which simplifies the process, reduces energy consumption and production costs, and produces products with excellent performance.

Abstract

The invention relates to the technical field of inorganic non-metallic materials, in particular to a method for producing electric melting zirconium oxide solid spheres by using a titration method. The method comprises the following steps: uniformly mixing zirconium oxide powder and a stabilizer to form a mixed raw material; and preparing a consumable electrode by adopting the mixed raw material, then melting the end part of the consumable electrode into zirconium oxide melt, and dripping to form the electric melting zirconium oxide solid ball. The method comprises the following steps: melting the end part of a consumable electrode to form a zirconium oxide solution, gathering the zirconium oxide solution into liquid drops with a certain size under the action of surface tension, and naturally dropping from the tail end of the electrode under the action of gravity to prepare the electric melting zirconium oxide solid sphere. The preparation method is short in technological process, and the prepared product is good in sphericity degree, high in density and uniform in chemical component.
