High Purity Brucite Magnesium Hydroxide

The chemical composition of Brucite, simple formula for Mg (OH) 2, brucite is very rare in the nature of high magnesite material, its theoretical chemistry MgO style, H2O, 69.12% and 30.55%, the nature of output water magnesium stone often impurities such as Fe, Mn, zinc, Ni, these impurities in class quality with like, the formation of the solid solution series of continuous or discontinuous, composition end-member subspecies: hot metal magnesium stone (including 10%) FeO, manganese brucite (MnO) 18%, zinc brucite (ZnO) 4%, nickel brucite (NiO) 2.5%. Brucite associated minerals have a serpentine, calcite, dolomite, magnesite, magnesium silicate minerals, periclase, diopside, talc and so on.. 

Composition of Brucite

Brucite is Natural Magnesium Hydroxide, also known as hydrated magnesia. Melting point (dehydration) 340 ° C, relative density: 2.39, hardness: 2.5, crystal structure: six crystal systems, relative molecular mass: 58.32, solubility: 0.009 g / L. Brucite has a simple chemical composition and its molecular formula is Mg(OH)2. Brucite is a rare high-magnesium mineral in nature. Its theoretical chemical composition is MgO 69.12% and H2O 30.55%. It is often found in brucites produced in nature. Impurities such as Fe, Mn, Zn, Ni, etc., these impurities exist as a homogeneous image, forming a series of continuous or discontinuous solid solution, constituent endmembers: iron brucite (including FeO 10%), manganese brucite (containing MnO 18%), zinc brucite (including ZnO 4%), nickel brucite (including NiO 2.5%). The associated minerals of brucite are serpentine, calcite, dolomite, magnesite, magnesium silicate mineral, periclase, diopside and talc.

Use of brucite

Brucite is an industrial mineral with special value due to its high content of useful components, low content of harmful impurities, and its unique physicochemical properties, which are different from other types of magnesium-containing mineral raw materials. The main uses of brucite is as below:

1. Flame retardant additives in rubber, plastic and fiber

2.  Flue gas desulfurization

3. Aluminum composite panel

4. Paper industry

5. Agriculture and fertilizer uses

6. Environmental protection field (Wastewater treatment)

7. Magnesia high temperature refractory

8. Fireproof coating

9. Neutralize the treatment agent and adjust the pH value
