Magnesium oxide (chemical formula MgO) has many uses in industry and everyday life, including:
1.Building materials: Part of building materials, such as cement, mortar and bricks. It provides strength and stability to the material and improves fire performance.
2.Fireproof material: Magnesium oxide has good fireproof performance, to make various fireproof materials, such as fireproof board, fireproof coating and fireproof mortar. It is not easy to burn at high temperature, and can play the role of heat insulation and flame retardancy.

3.Ceramic and glass industry: Magnesium oxide can be used as raw material for ceramic and glass industry. It can increase the compressive strength, wear resistance and corrosion resistance of ceramic and glass products.
4.Medicine and health products: In the production of medicine and health products. As an antacid and acid neutralizer to relieve discomfort from acid reflux and hyperacidity.
5.Water treatment agent: Can use as a water treatment agent to adjust the pH value and hardness of water. It can neutralize the acidic substances and metal ions in the water, and reduce the corrosion of equipment and pipelines caused by water quality.
6.Cultivated land improver: As a soil improver to adjust the acid-base balance of the soil and provide the magnesium element needed by plants.

NOTE: Relevant safety procedures should be when using magnesium oxide, such as avoiding inhalation of its dust, and avoiding contact with skin and eyes. In medicine and health care products, it should be in accordance with the doctor’s or manufacturer’s advice.
