Yellow Sand[2]
Overview
Yellow Sand is a naturally occurring granular material composed of finely divided rock and mineral particles, primarily silica. It is commonly found in deserts, riverbeds, and coastal areas. Due to its high silica content, it is widely used in various industrial applications, including construction and manufacturing. Yellow Sand is distinguished by its uniform particle size and chemical inertness, making it a versatile raw material. Its color ranges from yellow to beige, depending on the presence of iron oxides and other impurities. The material is typically mined and processed to meet specific industry standards.
Physical and Chemical Properties
Yellow Sand is chemically stable, with a high melting point of approximately 1713°C, making it suitable for high-temperature applications. Its density is around 2.65 g/cm³, and it is insoluble in water, acids, and alkalis under normal conditions. The material's particle size distribution is a critical factor in its industrial use. Fine particles are preferred for glass manufacturing, while coarser grades are used in construction. The high silica content (typically over 95%) ensures minimal reactivity, which is essential for consistent performance in various applications.
Main Applications
Yellow Sand is a key ingredient in the production of glass, where its high silica content ensures clarity and durability. It is also widely used in construction for making concrete, mortar, and asphalt. In foundries, it serves as a molding material for metal casting. Additionally, Yellow Sand is employed in water filtration systems due to its ability to trap impurities. Other applications include abrasives, ceramics, and hydraulic fracturing (fracking) in the oil and gas industry. Its versatility and abundance make it a staple in multiple sectors.
Safety and Storage
While Yellow Sand is generally non-toxic, prolonged inhalation of fine particles can cause respiratory issues. Workers should use dust masks and ensure proper ventilation in handling areas. Eye protection is also recommended to prevent irritation. Storage should be in a dry, well-ventilated space to prevent moisture absorption, which can affect its performance in certain applications. Bulk storage in silos or covered containers is ideal to minimize contamination and maintain quality.
B2B Procurement Guide
When procuring Yellow Sand, buyers should prioritize suppliers who provide detailed specifications, including silica content, particle size distribution, and impurity levels. Testing certificates from reputable laboratories can ensure compliance with industry standards. Pricing varies based on purity and processing level, with typical ranges between $50 and $150 per ton. Bulk purchases often qualify for discounts. Buyers should also consider logistics, as transportation costs can significantly impact the total procurement expense.
