  • Applications

    Disodium octaborate tetrahydrate is used in wood preservation as a termite and decay deterrent; in agriculture as a boron nutrient source for crops; in glass and ceramic manufacturing as a boron oxide source that supports fluxing and glaze stability; as a flame-retardant additive in certain polymer, textile, and paper formulations; and in some cleaning formulations as a borate-based builder or pH stabilizer, with actual use depending on formulation and regulatory constraints.
