JSP Boric Acid Powder ? 1 LB Jar? 99.9% Pure Anhydrous H?BO? ? Industrial Grade Our JSP Boric Acid is a high-purity, industrial-grade anhydrous powder with a minimum purity of 99.9%, packaged in a secure 1 LB reclosable jar for ease of use and storage. This finely milled white powder dissolves easily in water and has a wide range of practical and industrial applications ? including critical use in gold and precious metal refining. ? Used in Gold Precious Metal Refining Acts as a flux component during melting to reduce oxidation and form a glassy layer that traps impurities Helps protect molten metals from air exposure and enhances metal purity Often used in combination with other fluxes for smelting gold, silver, and platinum group metals Commonly used on crucibles, melting dishes, and furnace linings to create a non-stick barrier ?? Additional Uses: pH buffer for pools and hydroponic systems Fire retardant for fabrics and construction materials Neutron absorber in nuclear applications Used in steel hardening to extend tool life Effective as a preservative and mild antiseptic Also used in glassmaking, ceramics, and as a precursor to other boron compounds ? Naturally Occurring Water Soluble Boric acid is found naturally in the environment ? in soil, water, and plants. It?s also a source of boron, a micronutrient essential for plant growth. In water, it dissolves and can move through soil or substrates, making it suitable for agricultural and lab-grade applications. ?? Important Notes: For industrial and refining use only ? not for food or drug applications Store in a cool, dry place in the original sealed bag Keep out of reach of children
