brucite ore 2

White hexagonal crystal or amorphous powder. Water solution is alkaline, the Relative density is2.36g/ cubic meters. It can solute in acid and ammonium salt, almost insoluble in water and alcohol. In water solubility degree (18 °C)is 0009g / 100g . Easy to absorb carbon dioxide in the air. At 350 °C,decomposed into magnesium oxide and water. Above 500 °C, lose water into magnesium oxide.

According to different applications and special requirements, Our company has already researched and developed the productions of magnesium hydroxide such as industrial grade, agriculture and fertilizer grade, glass-making grade, flame grade, flame retardant grade, medicine and food grade, pharmaceutical grade, paste, and other varieties of twenty.

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
