Sand Acid Washed Extra Pure is a highly purified silica sand, treated with acid to remove impurities such as iron oxides and organic materials. It is an off-white granular solid primarily composed of silicon dioxide (SiO₂), characterized by its high purity and inertness. The acid washing process improves its adsorption capacity and surface cleanliness, making it ideal for use as a drying agent, filtration medium, and catalyst support in both laboratory and industrial applications. Due to its low solubility and high thermal stability, it serves in high-temperature processes and sensitive purification techniques. While chemically inert, the fine dust generated can pose respiratory hazards due to crystalline silica content; hence, proper handling precautions are essential. It remains stable under normal storage conditions, requiring dry and sealed containment to preserve its properties.
