Abstract

The invention discloses a production process for nanometer zirconium oxide powder. The production process comprises the following steps: S1, preparing three transparent beakers, each with a volume of 100 ml, in advance; S2, putting a certain gram of ZrOCl2. 8H2O into one of the transparent beakers prepared in the step S1; S3, adding 20 ml of clear water into the transparent beaker containing ZrOCl2. 8H2O prepared in the step S2 to dissolve the ZrOCl2. 8H2O; S4, adding a certain gram of NH4HCO3 into another transparent beaker prepared in the step S1; S5, adding 20 ml of clear water into the transparent beaker containing the NH4HCO3 prepared in the step S4 to dissolve the NH4HCO3; and S6, adding 5 ml of clear water into the last transparent beaker with the volume of 100 ml prepared in the step S1. According to the invention, ZrOCl2. 8H2O and NH4HCO3 are adopted as raw materials in the production process, a zirconium oxide precursor, namely zirconium oxycarbonate is generated through reaction in the solution, so harmful gas HCL generated by directly calcining ZrOCl2. 8H2O is eliminated, people are effectively prevented from inhaling the harmful gas during working, the production safety of workers is ensured, and potential safety hazards are effectively reduced.

Description

technical field [0001] The invention discloses a production process of nano zirconia powder, which belongs to the technical field of production of nano zirconia powder. Background technique [0002] Zirconia generally refers to zirconium dioxide, the chemical formula is ZrO2, which is the main oxide of zirconium. It is usually a white, odorless and tasteless crystal, which is insoluble in water, hydrochloric acid and dilute sulfuric acid. The chemical properties are inactive, and it has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient, making it an important high temperature resistant material, ceramic insulating material and ceramic sunscreen, and also the main raw material for artificial drills, because Zirconia has a large refractive index, high melting point, and strong corrosion resistance, so it is used as a kiln raw material. Piezoelectric ceramic products include filters, speakers, ultrasonic underwa...
