Aluminium Hydroxide
Formula : Al(OH)3
Description
Aluminium Hydroxide is a white, crystalline, amphoteric compound widely used for its flame-retardant, neutralizing, and stabilizing properties. Naturally occurring as the mineral gibbsite, it is valued for its chemical inertness, non-toxicity, and multifunctional applications. With roles in pharmaceuticals, water treatment, flame-retardant systems, and industrial processes, Aluminium Hydroxide is a versatile and essential raw material across industries.
