Which is better magnesium oxide or magnesium hydroxide?-2
3. Industrial Applications
The uses of magnesium hydroxide and magnesium oxide in industry are also different. Magnesium oxide is often used in refractory materials such as refractory bricks, furnace linings and cement manufacturing due to its high melting point and stability. It is also a common desiccant and desulfurizer, especially in high temperature environments, magnesium oxide can effectively absorb moisture and neutralize acidic gases.
Magnesium hydroxide is often used in water treatment, air purification and certain chemical reactions. Due to its low solubility, magnesium hydroxide can slowly release magnesium ions, adjust the pH of the solution, and is widely used in the neutralization treatment of industrial wastewater. In addition, the application of magnesium hydroxidein fireproof materials also has certain advantages, especially in the manufacturing process of plastics and wires and cables. As a flame retardant, magnesium hydroxide can improve the fire resistance of materials and reduce the spread of fire.
4. Environmental Protection
In the field of environmental protection, both magnesium oxide and magnesium hydroxide have important applications. Magnesium oxide can be used as a desulfurizer to absorb sulfur dioxide in flue gas and reduce air pollution. Magnesium hydroxideis particularly outstanding in water treatment, and can improve water quality by adjusting the pH value of water and removing heavy metal ions.
5. Summary
To sum up, magnesium hydroxide and magnesium oxide each have their own unique advantages and applicable scenarios:
Magnesium hydroxide: In medicine, it is used as an antacid and laxative with fewer side effects and is suitable for long-term use; in industry, it is used for water treatment and air purification, and performs well as a flame retardant. Its low solubility makes it perform better in many situations that require slow action.
Magnesium oxide: It is more suitable for situations that require rapid response, such as rapid neutralization of gastric acid, or as a refractory material, desulfurizer and other industrial applications. Its higher solubility and stronger acid neutralization ability make it more efficient in rapid acid neutralization, but it may cause gastrointestinal discomfort when used for a long time.
