Overview
Boric Acid Powder (H₃BO₃) is a white, odorless crystalline compound widely used across industrial, agricultural, and specialty applications. With its molecular weight of 61.83 g/mol and CAS number 10043-35-3, this versatile boron compound offers excellent solubility properties, dissolving readily in hot water and exhibiting mild acidity with a pH of 5.1 in solution. Its thermal stability, decomposing at 300°C, makes it suitable for high-temperature applications while maintaining safety in standard processing conditions.
Key Applications
- Flame Retardant: Essential component in fire-resistant materials, textiles, and building products, providing effective thermal protection without compromising material integrity.
- Glass and Ceramics Manufacturing: Critical ingredient in borosilicate glass production, improving thermal shock resistance and reducing thermal expansion in laboratory glassware and industrial applications.
- Agricultural Solutions: Used as a micronutrient in fertilizers to prevent boron deficiency in crops, promoting healthy plant growth and improved yields.
- Antiseptic and Pest Control: Functions as a mild antiseptic in pharmaceutical applications and serves as an effective insecticide for controlling various pests.
Safety & Handling
Boric acid powder presents minimal fire hazards with no flash point or autoignition temperature. Handle with standard laboratory personal protective equipment including safety glasses, gloves, and dust masks to prevent inhalation of fine particles. Ensure adequate ventilation when processing large quantities to minimize airborne dust exposure. The compound is generally considered low toxicity but should be kept away from food contact surfaces and out of reach of children.
Storage & Shelf Life
Store boric acid powder in tightly sealed containers in a cool, dry environment away from moisture and incompatible materials. Avoid contact with strong bases and reactive metals. When properly stored in original packaging or appropriate chemical storage containers, the product maintains indefinite shelf life under normal warehouse conditions. Protect from humidity to prevent caking and maintain free-flowing powder characteristics.
