Brucite frequently precipitates in fibrous foliated masses but can also grow as broad, tabular crystals that form rosettes. Its color varies. Most often it appears in somewhat drab shades of white, pale green, gray, or bluish-gray. But when it contains a significant amount of manganese (substituting for magnesium), that color may vary from yellow to brown or red.
In recent years, particularly attractive yellow specimens have hit the mineral collecting market. Whatever the outward color, brucite leaves a white streak on a streak plate and has a waxy, vitreous, or pearly luster. At 2 to 2.5 on the Mohs scale, it is very soft.
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
