Potassium fluorozirconate ( K₂ZrF₆) is an inorganic compound that typically appears as a colorless to white crystal or powder. It is a strong acid and alkaline salt with high thermal stability, which can be stable in the air, but will absorb moisture in humid environments.

The preparation of potassium fluorozirconate is usually obtained by reacting zirconium metal or its oxide with hydrofluoric acid, and the resulting zirconium fluoride is obtained by reacting with potassium hydroxide. It has a variety of uses in industry, especially in fields such as ceramic, glass, and metal surface treatment.

1. Ceramic industry: potassium fluorozirconate is used as a flux and emulsifier for ceramics, which helps to improve the sintering performance, mechanical strength and thermal stability of ceramics. It is also used in the production of special types of ceramics, such as electronic ceramics and bioceramics.

2. Glass Manufacturing: In glass production, potassium fluorozirconate can improve the chemical stability, mechanical strength, heat resistance, and acid resistance of glass. It is also used in the production of optical glass to improve the refractive index and transparency of glass.

3. Metal Surface Treatment: Potassium fluorozirconate can be used as a cleaner and corrosion inhibitor for metal surfaces, helping to remove oxides and contaminants from metal surfaces, as well as preventing metal corrosion during electroplating and metal processing.

4. Catalysts and catalyst carriers: Potassium fluorozirconate can be used as catalysts and catalyst carriers in chemical synthesis for reactions to produce organic compounds and polymers.

5. Paints and coatings: Potassium fluorozircnate is used in the production of special paints and coatings to improve the durability and chemical resistance of products.

6. Precision casting: In the field of precision casting, potassium fluorozirconate can be used as a component of refractory materials to make sand molds and shell molds for casting to improve the accuracy and quality of castings.

7. Mining: Potassium fluorozirconate is used as a flotation agent in the mining industry to help separate and extract valuable minerals.

8. Fluoride production: Potassium fluorozircon is an important raw material for the production of other fluoride compounds, such as aluminum fluoride, sodium fluoride, etc.
