Rutile sand is a mineral primarily composed of titanium dioxide (TiO2) and is commonly found in loose, granular form or as sand-sized grains. It possesses a tetragonal crystal structure and exhibits a prismatic or needle-like habit.

Key quality considerations for rutile sand products include:

1. Titanium content: The primary value of rutile sand lies in its titanium content. High-quality rutile sand should have a higher titanium content, which contributes to the extraction of premium-grade titanium dioxide and other products.
2. Impurities: High-quality rutile sand should have minimal impurities. Excessive impurities can affect the extraction process and the purity of the final product.
3. Particle size: The particle size of rutile sand is an essential quality factor. The product’s particle size should meet production and processing requirements, ensuring the quality of the final product.
4. Color: Rutile sand can come in a variety of colors, such as golden yellow, reddish-brown, black, or iron black. The color variations can impact its suitability for different applications, including industrial or gemological uses.
5. Hardness: Rutile sand’s hardness is important for its use as an abrasive or in other applications. The appropriate hardness enhances the product’s abrasion resistance and lifespan.
6. Loss on ignition: Loss on ignition refers to the weight loss of rutile sand at high temperatures. Low loss on ignition usually indicates higher purity.
7. Chemical reactivity: For certain applications like ceramics, rutile sand may require specific chemical reactivity and compatibility. Quality assessment involves testing its chemical reactivity and compatibility.
8. Source and supply chain: Quality judgment for rutile sand products also involves considering their source and supply chain management. Ensuring reliable suppliers, compliant extraction methods, and consistent quality are crucial.

By carefully evaluating these factors in the production and use of rutile sand products, it ensures that the material performs exceptionally in applications such as titanium dioxide production, ceramics, coatings, plastics, rubber, and other industries.
