Fused cast zirconia refractory product as well as preparation method and application thereof

Abstract

The invention provides a fused-cast zirconia refractory product and a preparation method and application thereof, the fused-cast zirconia refractory product is a fused-cast zirconia brick product impregnated in a solution A, the fused-cast zirconia brick product contains a glass phase, and the zirconium content is greater than or equal to 88% or greater than or equal to 92%; the solution A comprises zircon salt and is prepared by the following steps: dissolving ethyl silicate in an organic solvent and water; adding zirconium nitrate, zirconium carbonate, ammonium zirconium carbonate or zirconium acetate, dissolving, and uniformly stirring, with the volume ratio of the organic solvent to water being 3: 80-95 and the molar ratio of Si to zirconium being (5-10): (90-95); adding nitric acid under a stirring condition, and adjusting the pH value to 5-6 to obtain a solution A; wherein the concentration of the solution obtained after the ethyl silicate is dissolved in the organic solvent and the water is 0.001-0.05 mol / L. The seepage of a glass phase in the fused-cast zirconia product is reduced or prevented by infiltrating the fused-cast zirconia product into a solution containing zircon salt, and the performance of the fused-cast zirconia product as a refractory product is further improved at the same time.

Description

technical field [0001] The invention relates to a zirconia refractory product, in particular to a fused-cast zirconia refractory product, a preparation method and an application. High zirconium bricks and their glass phases are directly related to the production of high-purity glass. Vaccine bottles are unqualified because the glass body seeping from the wall of the glass melting furnace enters the glass to form impurities, resulting in unqualified vaccine bottles. The quality of zirconia refractory products The quality is directly related to the quality of vaccine bottles, so it is urgent to improve the quality of zirconia refractory products. Background technique [0002] High zirconium bricks and their glass phases are directly related to the production of high-purity glass. Vaccine bottles are unqualified because the glass body seeping from the wall of the glass melting furnace enters the glass to form impurities, resulting in unqualified vaccine bottles. The quality of ...
