What is 90% Silica Sand?

Silica sand, also known as quartz sand or industrial sand, is composed primarily of silicon dioxide (SiO2). The designation of ’90 silica sand’ refers to a grade where the silicon dioxide content is approximately 90%, with the remaining 10% comprising other minerals and impurities. The quality and specific properties of silica sand are determined by its grain size, shape, color, and the type and amount of impurities present. For 90% silica sand, the acceptable impurities are typically iron oxides, feldspar, clay, and other trace elements, which, in small quantities, do not significantly hinder its performance in many industrial applications.

The source of silica sand plays a critical role in its composition and purity. It is typically derived from inland sand deposits or harvested from coastal and marine locations. The geological processes that form these deposits influence the final characteristics of the sand. For instance, the degree of silica dissolution and reprecipitation, as well as the presence of heavy minerals, can affect purity levels. The processing typically involves washing, screening, and sometimes drying to meet specific industrial requirements. Understanding these natural variations is important when sourcing 90% silica sand for consistent results.

The 90% purity level strikes a balance between cost and performance for many applications. While higher purity silica sand (e.g., 99% or more) is required for specialized uses like high-grade glass manufacturing or semiconductor production, the 90% grade is perfectly adequate and more economical for a broad spectrum of uses. These include construction materials like concrete and mortar, filtration media, foundry casting, and abrasive applications. The consistent availability and cost-effectiveness of 90% silica sand make it a preferred choice for large-scale industrial operations.

Importance of Purity and Grain Size

The purity of silica sand is paramount as it directly impacts the physical and chemical properties of the final product or process. For 90% silica sand, the primary concern is that the impurities do not negatively affect its intended function. For example, in construction, excessive clay content can affect workability and strength, while high iron content can lead to discoloration in certain applications. Grain size and shape are equally critical. Uniform grain sizes ensure consistent packing density in filtration media, while angular grains might be preferred for foundry molds to provide better interlocking and stability.

• Construction Grade Silica Sand: This is perhaps the most common application. 90% silica sand is a key aggregate in concrete, mortar, stucco, and asphalt mixes. It provides bulk, strength, and durability to these building materials. Its grain size is crucial for achieving the desired workability and finish in construction projects.
• Foundry Sand: In metal casting, silica sand is used to create molds and cores. The high silica content and refractoriness of the sand allow it to withstand the high temperatures of molten metal. The 90% grade is suitable for many general casting applications, providing good dimensional stability for the cast parts.
• Filtration Sand: Due to its granular nature and chemical stability, silica sand is widely used as a filter medium in water treatment plants, swimming pools, and industrial filtration systems. The 90% purity is often sufficient for effective particle removal, and its grain size can be controlled to target specific filtration rates and efficiencies.
• Abrasive Sand: Silica sand is used in sandblasting and other abrasive applications for cleaning, surface preparation, and etching. Its hardness and abrasive properties make it effective for removing rust, paint, and other surface contaminants. Proper safety precautions are essential due to the potential for silica dust inhalation.
• Chemical Production: While higher purity sand is often preferred, 90% silica sand can be used as a raw material in certain chemical processes where extreme purity is not a critical factor. It can serve as a source of silicon dioxide for producing sodium silicate or other silicon-based chemicals.

The specific application often dictates the exact specifications required, even within the 90% purity range.

How to Choose the Right 90% Silica Sand

Selecting the appropriate grade of 90% silica sand is critical for achieving the desired outcomes in any industrial or construction application. The seemingly simple material has nuanced properties that, when matched correctly to the need, ensure efficiency, durability, and cost-effectiveness. In Corpus Christi, with its diverse industrial base ranging from port operations to manufacturing, understanding these selection criteria is vital for businesses.

Key Factors to Consider

1. Purity Level: While the target is 90% silica sand, understanding the exact percentage of SiO2 and the nature of the remaining 10% impurities is essential. For instance, iron content can cause discoloration, which is undesirable in decorative concrete or white mortars. Clay or silt content can affect water retention and workability in construction mixes.
2. Grain Size Distribution (Mesh Size): This is arguably the most crucial factor. Different applications require different grain sizes. For example, finer sands (higher mesh numbers) are used for smooth finishes in plaster or as fine filter media, while coarser sands (lower mesh numbers) provide bulk and strength in concrete and asphalt. A well-graded sand, with a mix of sizes, often provides better packing density and stability.
3. Grain Shape: Silica sand grains can be rounded, sub-rounded, sub-angular, or angular. Rounded grains are common in naturally eroded river or beach sands and are good for flowability (e.g., in hydraulic fracturing). Angular or sub-angular grains, often found in crushed quartz or certain consolidated deposits, interlock better and provide greater strength and stability in construction materials like concrete and mortar.
4. Hardness and Durability: Silica sand is inherently hard (Mohs hardness of 7), making it suitable for abrasive applications and durable in construction. However, the presence of softer impurities could compromise its performance under stress or abrasion.
5. Moisture Content: The amount of moisture in the sand can affect its weight and handling properties, especially when sold in bulk. For some applications, like certain types of concrete or specialty mixes, precise moisture control is necessary.
6. Source and Consistency: Understanding the origin of the sand and the consistency of its quality from batch to batch is important for industrial processes that rely on predictable material performance. Sourcing from reputable suppliers who maintain strict quality control is key.
