About Zircon Flour

Ever since our establishment in 2004, we are serving our respected clients by offering them supreme-grade Zircon Flour. It is prepared by precise milling of zircon sand either in the dry state or in a slurry. There are many areas where this flour is utilized such as ceramic frits, foundry mold coatings, shells for investment casting, insulating fibers, glass, and different friction products. The offered Zircon Flour is packed in bulk bags or paper sacks. In addition to this, we offer this flour in different mesh sizes at industry-leading price.

Features:

High melting and boiling points
Insoluble in water and other solvents
Chemically inert nature

Superior Performance in High-Temperature Applications

Engineered to withstand extreme thermal conditions, Zircon Flour demonstrates exceptional refractoriness under load (RUL >1700C) and a high melting point around 2350C. Its fine, smooth surface finish and low thermal conductivity make it a preferred choice for technologies demanding stability and insulation at elevated temperatures, such as in kiln linings, precision casting molds, and specialized foundry coatings.

Consistent Quality and Minimum Impurities

With a minimum purity of 98%, low moisture content, and negligible loss on ignition, Zircon Flour ensures minimal contamination in sensitive applications. Elemental impurities like Fe2O3 and TiO2 are both strictly controlled at a maximum of 0.10%. Its low porosity and nil water absorption further contribute to excellent mechanical and chemical properties.

FAQs of Zircon Flour:

Q: How is Zircon Flour typically used in industrial applications?

A: Zircon Flour is widely used in ceramics (as a glaze opacifier), refractory products (bricks and linings), precision investment casting molds, foundry coatings, glass manufacturing, abrasives, and pigments. Its high temperature stability and mechanical strength make it invaluable in processes that require thermal resilience and fine finishes.

Q: What advantages does Zircon Flour offer compared to other refractory materials?

A: Zircon Flour boasts high mechanical strength, superior refractoriness (>1700C), minimal water absorption, and excellent dimensional stability at high temperatures. Its low thermal conductivity and very low porosity lead to greater energy efficiency and improved durability in high-stress industrial environments.

Q: When should Zircon Flour be selected over alternative materials?

A: Zircon Flour is preferred whenever applications demand high purity, fine particle size, and resilience to extreme temperaturessuch as in precision casting molds, advanced refractories, and ceramic glazes. It is particularly effective where surface finish, thermal insulation, and stability under heat load are critical.

Q: What is the recommended process for handling and storing Zircon Flour?

A: Zircon Flour should be handled in well-ventilated areas and stored in its original, tightly sealed 25 or 50 Kg HDPE bags to prevent moisture ingress. Care should be taken to keep the material dry and uncontaminated, away from acids or alkaline substances that could affect its properties.

Q: Where is Zircon Flour sourced and supplied in India?

A: In India, Zircon Flour is available through distributors, importers, manufacturers, suppliers, and traders. It is widely distributed to cater to the requirements of the ceramics, foundry, refractory, glass, and pigment sectors.

Q: What are the key chemical and physical properties of Zircon Flour?

A: Zircon Flour contains at least 65% ZrO2 + HfO2, up to 33% SiO2, and a maximum of 0.10% each for TiO2 and Fe2O3. With a density of 4.7 g/cm, specific gravity of 4.44.7, and Mohs hardness 77.5, it features a pH between 7.08.5, no water absorption, and virtually zero porosity.
