Product Description

Product Description

Magnesium Hydroxide Introduction

Definition

Magnesium hydroxide is an inorganic compound composed of magnesium, oxygen, and hydrogen. With the chemical formula Mg(OH)2, it is commonly known as milk of magnesia in its suspension form. This compound is recognized for its applications in multiple industrial and consumer - related fields.

Physical and Chemical Properties

1. Physical: It appears as a white solid powder with low solubility in water. It has a density of around 2.34 g/cm³ and a melting point that decomposes before reaching a true melting state due to thermal decomposition.
2. Chemical: As a base, it reacts with acids to form salts and water. It also decomposes into magnesium oxide and water when heated at high temperatures.

Production Methods

1. Precipitation Method: Reacting magnesium - containing salts (like magnesium chloride) with NaOH in an aqueous solution to precipitate magnesium hydroxide.
2. From Seawater: Extracting magnesium ions from seawater, then reacting them with a base such as NaOH or NH3 to produce magnesium hydroxide.

Storage

1. Store in a dry, cool place to avoid moisture - related reactions.
2. Keep away from acidic substances to prevent chemical reactions.
3. Use sealed containers to protect it from air and moisture.

Market Information

The market for magnesium hydroxide is expanding, driven by its increasing use in flame retardants and water treatment. The price is affected by the cost of raw materials, especially magnesium - rich ores and alkalis.

Downstream Industries

1. Flame Retardants: Used in plastics, rubber, and textiles to enhance fire resistance.
2. Water Treatment: As a pH adjuster and for removing heavy metals from wastewater.
3. Cosmetics: Added to some products for its soothing and anti - irritation properties.

Application

Uses of Magnesium Hydroxide

1. Flame Retardant: In the manufacturing of building materials, electrical appliances, and automotive parts, magnesium hydroxide decomposes upon heating, releasing water vapor that dilutes flammable gases and cools the burning surface, thus preventing the spread of fire.
2. Water Treatment: It adjusts the pH of acidic wastewater, making it neutral or slightly alkaline. Also, it can react with heavy metal ions to form insoluble precipitates, facilitating their removal from water.
3. Cosmetics: In skincare products, it helps soothe irritated skin, reduces redness, and acts as a mild exfoliant in some formulations.
4. Agriculture: Used as a soil amendment to adjust soil pH, especially in acidic soils, providing magnesium nutrients to plants and improving soil structure for better root growth.
