get started and magnesium hydroxide both exhibit excellent anti-corrosion effects,but there are differences in specific applications and performance.The following is a detailed comparison of the anti-corrosion effects of these two compounds:

Application Fields

Magnesium oxide:mainly used as an anti-corrosion coating on concrete surfaces.

Magnesium hydroxide:widely used as a flame retardant in plastic and rubber products,and as a flue gas desulfurizer in environmental protection.

Anti corrosion mechanism

Magnesium oxide:By forming an alkaline surface layer,it prevents acidic substances from corroding concrete.

Magnesium hydroxide:slows down flame propagation by absorbing heat and releasing water molecules,while neutralizing acidic and corrosive gases produced during combustion.

Physical and chemical stability

Magnesium oxide:has good chemical stability and is not easily reactive with other substances.

Magnesium hydroxide:When heated to 350℃,it loses water and forms magnesium oxide,but is relatively stable at room temperature.

Environmental friendliness

Magnesium oxide:non-toxic and harmless,environmentally friendly.

Magnesium hydroxide:It also has the characteristics of non-toxic,odorless,and non corrosive,and is a green and environmentally friendly additive for polymer materials.

Overall,magnesium oxide and magnesium hydroxide each have advantages in the field of corrosion prevention.Magnesium oxide is more suitable for applications that require high durability and chemical stability,while magnesium hydroxide is widely used in polymer materials such as plastics and rubber due to its excellent flame retardant and smoke suppression properties.
