MgO Brucite Magnesium Hydroxide Granular for Fertilizer

Brucite is called Natural Magnesium Hydroxide, molecular formula is Mg(OH)2,shows itself in white or white gray color.

There are wide applications for brucite, it is not only a kind of high grade refractory materials but also the best material for make magnesium metal. Due to its good fire retardancy, it is ideal not-toxic, smokeless, non-polluting flame retardant. Brucite can be usde as the raw material for making nucleus reactor's protecting material; it can  be used for soil improvement and also regulating PH value. Naturally it can be directly used as raw material for making lightweight Magnesium Oxide, magnesium oxide and magnesia cement.

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
