1309-42-8/Magnesium hydroxide

Industrial Uses

Magnesium hydroxide (Mg(OH)2) is utilized in various industrial sectors such as food processing, paper production, heritage preservation, and as a flame-retardant material.

Antimicrobial Potential

Mg(OH)2 is hailed as a cheap and biocompatible material with antimicrobial properties.

Diverse Morphology and Applications

Mg(OH)2 exhibits diverse particle morphologies, such as needles, platelets, rods, spheres, flowers, and stars, making it suitable for various modern and advanced material applications, including flame-retardants, heavy metal precipitants, acidic waste neutralizers, antibacterial agents, cultural heritage protective agents, chemical sensors, and medicine production. It is also an important precursor for the synthesis of magnesium oxide (MgO).

Coating Substance for Environmental Remediation

Its special features, including low cost, high surface area, non-magnetization, and low solubility constant, make it an excellent coating substance for enhancing the performance of nanoscale zero-valent iron (nZVI) in environmental remediation efforts.

Synthesis Methods

Mg(OH)2 particles can be produced through various methods including precipitation, solvothermal and hydrothermal methods, microwave methods, electrochemical methods, sol-gel method, and hydration of MgO. The precipitation method is commonly used due to its low cost and simplicity. The properties and morphology of Mg(OH)2 materials depend on the type of precursor and precipitating agent used, as well as the synthesis process parameters.

Petallike Morphology

Petal-like Mg(OH)2 materials have larger specific surface areas and higher decomposition temperatures, making them favorable for heavy-metal adsorption and flame retardancy. Significant attention has been given to synthesizing petal-like Mg(OH)2 materials.

Carbonation and Cementitious Component

Mg(OH)2 can gain strength through carbonation, presenting potential for its use as a cementitious component. Its utilization as a cementitious binder can provide permanent CO2 sequestration within building components.

General Description

Magnesium hydroxide, also known as milk of magnesia, is a compound that consists of magnesium, oxygen, and hydrogen. It is a white, powdery substance that is commonly used as an antacid and laxative to relieve constipation and neutralize stomach acid. When taken orally, it reacts with the hydrochloric acid in the stomach to form magnesium chloride and water, thereby reducing the acidity in the stomach and providing relief from heartburn and indigestion. It is also used as a component in some deodorants and as a flame retardant in various materials. Additionally, magnesium hydroxide has applications in water treatment and as a precursor to other magnesium compounds.
