Asbestos, acid washed, is a purified form of asbestos fibers treated with acid to remove impurities, resulting in low solubility and suitability for analytical and industrial applications. In laboratory settings, it is commonly used as a filtering aid in Gooch crucibles and other filtration setups due to its chemical inertness, heat resistance, and minimal solubility in acids and water. Industrially, it is employed in the manufacturing of fireproof materials, such as protective clothing, insulation for pipes and boilers, and fire blankets, owing to its durability and insulating properties. Additionally, it is utilized in the production of gaskets, brake linings, and clutch facings in automotive industries for its ability to withstand high temperatures and friction. In construction, it is integrated into cement products, roofing materials, and floor tiles to enhance strength and fire resistance. However, its use is heavily regulated or banned in many countries due to severe health risks associated with asbestos exposure, such as lung diseases and cancer. Handle with extreme caution using proper PPE and ventilation.
