Key Features and Applications

Di-boron Trioxide stands out for its high purity (99%) and stability as a fine, white powder. Its primary uses include manufacturing specialty glasses and ceramics, serving as a fluxing agent in metallurgical processes, and acting as a reagent in chemical synthesis. Its partial solubility and acidicity enhance its effectiveness in these domains. As it is non-flammable and inert with respect to most materials (except strong acids and bases), Di-boron Trioxide is suitable for diverse industrial purposes.


Safe Handling and Storage Guidelines

While handling Di-boron Trioxide, appropriate safety measures should be taken as it can cause irritation to the eyes, skin, and respiratory tract. Personal protective equipment such as gloves and goggles is recommended. Store the product in a tightly sealed container in a cool, dry location, away from strong acids and bases. Proper storage ensures a shelf life of up to 36 months, maintaining product integrity for extended use.
