Magnesium Oxide White Powder

Detail Specification

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: Application of magnesium oxide in fireproof materials

Magnesium oxide (MgO) has the following advantages in fireproof materials due to its unique physical and chemical properties:
1. Excellent fire resistance
High melting point and thermal stability: Magnesium oxide has a melting point as high as 2852°C, which is much higher than other commonly used fireproof materials, which allows it to maintain structural stability in high temperature environments without melting or decomposing. According to the refractory industry standards, the fire resistance of magnesium oxide products can reach more than 2000°C, which makes it an ideal fireproof material in high-temperature industries and construction.
Good thermal insulation properties: Magnesium oxide has good thermal insulation properties, mainly due to its low thermal conductivity. Experimental data shows that under high temperature conditions, the thermal conductivity of magnesium oxide is only about 0.06 W/m·K, which is much lower than ordinary building materials. This means that magnesium oxide can effectively prevent heat transfer, thereby improving the fire insulation effect of the building.

2. Environmental performance
Non-toxic and harmless: Magnesium oxide itself is non-toxic and harmless, and does not release harmful gases at high temperatures, which is of great significance for improving the safety of buildings and the health of the living environment. According to data from environmental monitoring agencies, magnesium oxide fireproof materials will not produce harmful smoke in fires, which greatly reduces the threat of fires to personnel health.
Renewable and recyclable: Magnesium oxide comes from mineral resources found in nature, such as magnesite, which are abundant and renewable. Moreover, magnesium oxide products can be recycled and reused after their service life is over, which is of positive significance for the sustainable use of resources and environmental protection. According to resource reuse research, after proper treatment, the performance of recycled magnesium oxide materials is almost unaffected and can still be used in the production of fireproof materials.

3. Excellent stability
Chemical stability: Magnesium oxide has excellent chemical stability and can remain stable in various harsh environments, such as acid, alkali, salt spray, etc., and is not prone to chemical reactions. This enables magnesium oxide fireproof materials to be used for a long time in various extreme environments, ensuring the durability and safety of buildings.
Water stability: Magnesium oxide has good water stability and will not degrade or fail due to water absorption. This is particularly important for fire-resistant materials that need to be used in humid environments or outdoors. According to water stability test data, the structure and performance of magnesium oxide materials do not change significantly after long-term exposure to high humidity environments.

4. Multifunctional applications
As a fireproof board: Magnesium oxide is widely used to make fireproof boards. These boards have many advantages such as light weight, high strength, fire resistance, sound insulation, etc., and are suitable for various building parts such as walls, ceilings, and floors. According to the building materials market survey, magnesium oxide boards have gradually replaced traditional gypsum boards and cement boards and become the mainstream choice of building fireproof materials due to their superior comprehensive properties.
Used in fire-retardant coatings: Magnesium oxide can also be used to make fire-retardant coatings. These coatings can be coated on the surface of building structures to form a fire-resistant barrier, effectively improving the fire-resistance rating of the building. According to a fire-retardant coating research report, coatings added with magnesium oxide can form a stable protective layer in a fire, significantly extending the fire-resistant time of building structures and protecting the safety of buildings and personnel.

5. Economic benefits
Cost-effectiveness: Although the initial cost of magnesium oxide materials may be higher than some traditional fire-resistant materials, its excellent performance and long life make it more cost-effective throughout its life cycle. According to the economic benefit analysis, the use of magnesium oxide fireproof materials can reduce the frequency of maintenance and replacement and reduce the overall cost of use.
