Product DescriptionProduct DescriptionBoric Acid is an important inorganic acid with a unique chemical structure and mild acidity. It is widely used in industries such as industry, medicine, agriculture, and daily chemicals, and is a multifunctional chemical raw material.It is usually a white crystalline powder or flaky lustrous crystals, odorless, slightly sour in taste, and has a slippery feeling when touched. It is soluble in water, ethanol, glycerol, etc. The solubility in water significantly increases with the rise in temperature. At 20℃, the solubility is approximately 5.7g/100mL, and it can reach 37.4g/100mL at 100℃. The aqueous solution is weakly acidic, and the pH value of a 0.1mol/L solution is approximately 5.1.SpecificationTest ItemsIndustrial GradePharmaceutical GradeElectronic GradeAppearanceWhite crystalline powderWhite crystalline powderWhite ultra - fine powderAssay (H3BO3) (%)≥99.0≥99.5≥99.9Water Insoluble Matter (%)≤0.05≤0.02≤0.001Sulfate (as SO4) (%)≤0.1≤0.02≤0.0005Chloride (as Cl) (%)≤0.01≤0.005≤0.0001Iron (Fe) (%)≤0.002≤0.001≤0.00005Heavy Metals (as Pb) (%)≤0.001≤0.0005≤0.00001Arsenic (As) (%)≤0.0001≤0.00005≤0.000001Loss on Drying (%)≤0.5≤0.3≤0.1pH Value (1% Aqueous Solution)5.0 - 6.05.0 - 6.05.0 - 5.5Packing & DeliveryIndustrial-grade products are packaged in plastic woven bags or kraft paper bags lined with polyethylene film, with specifications of 25kg per bag and 50kg per bag.
