Magnesium oxide (chemical formula: MgO) is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in nature in the form of periclase and is the raw material for magnesium smelting.

Magnesium oxide has high fire-resistant insulation properties. It can be transformed into crystals after high-temperature burning above 1000°C, and it becomes dead-burned magnesium oxide (also known as magnesia) or sintered magnesium oxide when it rises to 1500-2000°C.
Magnesium oxide is commonly known as magnesia, also known as magnesium oxide. Magnesium oxide is an alkaline oxide with the common properties of alkaline oxides and belongs to a gelling material. White or light yellow powder, odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. White powder, melting point is 2852°C, boiling point is 3600°C, relative density is 3.58 (25°C). Soluble in acid and ammonium salt solution, insoluble in alcohol. When exposed to air, it easily absorbs water and carbon dioxide and gradually becomes basic magnesium carbonate. Light products react faster than heavy products. It combines with water under certain conditions to generate magnesium hydroxide, which is slightly alkaline. The pH of the saturated aqueous solution is 10.3. It is soluble in acid and ammonium salts, but difficult to dissolve in water. Its solution is alkaline. It is insoluble in ethanol. It has strong refractive properties in the visible and near-ultraviolet light range.
Magnesite (MgCO3), dolomite (MgCO3·CaCO3) and seawater are the main raw materials for the production of magnesium oxide. Magnesium oxide is obtained by thermal decomposition of magnesite or dolomite. Magnesium hydroxide precipitate is obtained by treating seawater with slaked lime, and magnesium oxide is obtained by burning magnesium hydroxide. Magnesium chloride brine blocks obtained from the comprehensive utilization of seawater or brine after bromine extraction can also be used as raw materials, and sodium hydroxide or sodium carbonate are added to generate magnesium hydroxide or basic magnesium carbonate precipitate, which is then burned to obtain magnesium oxide.

Precautions

Precautions for using magnesium oxide:

Fire prevention: Magnesium oxide is a flammable substance, so it needs to be handled with care and avoid contact with open flames. Fire extinguishers and fire protection equipment should be equipped when storing and using magnesium oxide.
Hygiene: Magnesium oxide may come into contact with the mouth, nose and eyes during use, so these parts need to be carefully protected. After use, the skin should be washed with soap and water immediately.
Operating environment: When operating magnesium oxide, it should be avoided in high temperature, high humidity and poor ventilation. At the same time, in order to avoid dust flying, personal protective equipment such as masks and goggles should be worn.
Safe storage: Magnesium oxide should be stored in a dry, ventilated and sun-proof place to avoid long-term exposure to the air. If stored improperly, magnesium oxide may deliquesce and deteriorate.
Quality control: In order to ensure the quality and performance of magnesium oxide, factors such as the selection of raw materials, processing process and storage conditions need to be controlled. When using magnesium oxide, raw materials that meet the requirements should be selected, and processing and storage conditions should be strictly controlled.

Product Knowledge: The types of magnesium oxide

Magnesium oxide (MgO) is an important inorganic compound that is widely used in various fields due to its diverse physical and chemical properties. Magnesium oxide can be divided into many types according to production process, purity, particle size and application requirements.

Magnesium oxide product types	Features and Applications	Production process
1. High purity magnesium oxide	High-purity magnesium oxide generally has a purity of more than 98% and is mainly used in industries that require high-purity raw materials, such as electronics, optics and medicine. In these applications, high-purity magnesium oxide is a key material that can ensure the performance and quality of the product.	High-purity magnesium oxide is usually prepared by electrolysis or calcination of high-purity magnesite. These processes can remove most impurities and ensure the high purity of magnesium oxide.
2. Activated magnesium oxide	Active magnesium oxide has a high surface area and strong chemical reactivity, and is usually used in catalysts, adsorbents and desulfurizers. It can effectively promote chemical reactions and improve production efficiency and product quality.	Active magnesium oxide is mainly prepared by controlling the calcination conditions. For example, calcining magnesium hydroxide or magnesium carbonate at a lower temperature can produce highly active magnesium oxide.
3. Light magnesium oxide	Light magnesium oxide is a low-density, fluffy magnesium oxide that is mainly used in rubber, plastics, building materials and chemical industries. Its low density and good dispersibility make it an ideal filler and modifier.	Light magnesium oxide is usually prepared by low-temperature calcination of magnesium carbonate or magnesium hydroxide, which can obtain a loose and porous structure.
4. Heavy magnesium oxide	Heavy magnesium oxide has a high density and strength and is mainly used in refractory materials, ceramics and metallurgical industries. It can remain stable in high-temperature environments and provide excellent refractory properties.	Heavy magnesium oxide is generally prepared by high-temperature calcination of magnesite. High-temperature calcination can increase the density and strength of magnesium oxide, making it suitable for use under high temperature conditions.
5. Fused magnesium oxide	Fused magnesium oxide is a high-density, high-purity magnesium oxide prepared by electric fusion, which is mainly used in advanced refractory materials and ceramic products. It has extremely high temperature resistance and corrosion resistance, and is suitable for high-temperature processes such as steel and non-ferrous metal smelting.	Fused magnesium oxide is made by melting high-purity magnesite or light-burned magnesium oxide in an electric arc furnace and then cooling and crystallizing. This process can produce magnesium oxide crystals with high purity and high density.
6. Food grade magnesium oxide	Food-grade magnesium oxide is required to be non-toxic and harmless, meet the standards of food additives, and is mainly used in the food industry and the pharmaceutical industry. It is often used as an anti-caking agent, acidity regulator, and nutritional enhancer.	Food-grade magnesium oxide is usually made by calcining high-purity magnesium hydroxide or magnesium carbonate. The impurity content needs to be strictly controlled during the production process to ensure that the product meets food safety standards.
7. Pharmaceutical grade magnesium oxide	Medical-grade magnesium oxide must meet the pharmacopoeia standards and is mainly used to prepare medicines, such as antacids, laxatives, etc. It plays a key role in pharmaceutical preparations to ensure the effectiveness and safety of drugs.	Pharmaceutical grade magnesium oxide is made from high-purity magnesium hydroxide or magnesium carbonate by calcining under strictly controlled conditions and undergoes multiple filtrations and refinements to ensure its purity and safety.
