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.
Yingkou Maomei Agricultural Technology Co., Ltd. is located in Yingkou Dashiqiao City in the central and southern part of Liaoning Province, which is famous at home and abroad as the "China Magnesium Capital". Yingkou Maomei Agricultural Technology relies on high-quality magnesite mineral resources to produce magnesium oxide powder and granules, which are widely used in refractory materials, medicine and health, fertilizers, feed, and industrial fields.

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: Production Process of Magnesium Oxide


Magnesium oxide (MgO) is an important inorganic compound, widely used in refractory materials, fertilizers, medicine, building materials and environmental protection. The production process of magnesium oxide varies according to different uses and needs. The main production processes include calcination, precipitation and electrolysis.
1. Calcination method: One of the most common methods for producing magnesium oxide, mainly divided into magnesite calcination method and magnesium hydroxide calcination method.
a. Magnesite calcination method: Magnesite (MgCO₃) is the main mineral raw material of magnesium oxide, which undergoes raw material processing, calcination, cooling and crushing. The advantage is that the raw materials are easy to obtain and the cost is low, but the calcination process requires high energy consumption and will produce carbon dioxide emissions, which has a certain impact on the environment.
b. Magnesium hydroxide calcination method: Mainly uses magnesium resources in seawater or bittern. It is made by magnesium hydroxide precipitation, filtration and drying, calcination, cooling and crushing. It has the advantages of relatively low energy consumption and high product purity, but the raw material cost is high and the process is relatively complicated.
2. Precipitation method: A method of directly generating magnesium oxide through chemical reaction.
a. Salt precipitation method: Soluble magnesium salts (such as magnesium sulfate and magnesium chloride) are reacted with alkali to generate magnesium hydroxide precipitation, which is then converted into magnesium oxide through calcination. The production steps include dissolution and reaction, filtration and drying, and calcination.
b. Hydrothermal synthesis method: React in a high-pressure and high-temperature aqueous solution to generate nano-magnesium oxide. The production steps include reaction solution preparation, hydrothermal reaction, calcination and cooling. The hydrothermal synthesis method can produce magnesium oxide with small particle size and large specific surface area, but the equipment cost is high and it is suitable for the production of high value-added products.
3. Electrolysis method: A method of generating magnesium oxide by electrolyzing molten magnesium salt. Its production includes magnesium salt melting, electrolysis, cooling and collection. The electrolysis method can produce high-purity magnesium oxide with precise process control, but the energy consumption is high and it is mainly used for high-end applications.
