Magnesium Oxide

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: Advantages of magnesium oxide in fertilizer applications

The application of magnesium oxide in chemical fertilizers has the following significant advantages:
1. Provide important nutrients
Magnesium is the core component of chlorophyll, participates in photosynthesis, and is essential for the growth and development of plants. According to research, a lack of magnesium can cause plant leaves to become chlorotic, affecting photosynthetic efficiency, thereby affecting yield and quality. The use of fertilizers containing magnesium oxide can effectively replenish magnesium in the soil, promote healthy growth of crops, and increase crop yield and quality.
2. Efficient soil conditioning effect
In acidic soils, plant growth is restricted and nutrients are easily lost. Magnesium oxide, as a strong alkaline substance, can effectively neutralize acidic components in the soil and adjust the pH value of the soil. According to experimental data, applying 1 ton of magnesium oxide per hectare of land can increase the soil pH by about 1 unit, thus improving the soil environment and promoting nutrient absorption by crops. Magnesium oxide can improve the physical structure of the soil and enhance the soil's aggregate structure, thereby improving the soil's air permeability and water retention. This is particularly important for sandy soil and clay soil, which can effectively improve the drought resistance and stress resistance of crops and ensure the stable growth of crops.
3. Environmental performance
Magnesium oxide itself is non-toxic and harmless and will not pollute soil, water and crops. It is not easily lost in the soil, remains effective for a long time, and is environmentally friendly. According to a report by the environmental protection agency, the use of magnesium oxide fertilizer will not increase the content of heavy metals in the soil and meets the requirements of green agriculture. Magnesium oxide can effectively reduce the loss of nitrogen, phosphorus, potassium and other nutrients in the soil. Research shows that magnesium oxide can form stable compounds with nitrogen and phosphorus in the soil, reducing the risk of nutrient loss with rainwater and improving fertilizer utilization. This not only helps protect the environment, but also improves the economic benefits of fertilizers.
4. Economic benefits
Magnesium oxide can promote crop growth, enhance photosynthesis and increase yield. According to agricultural test data, crop yields increase by an average of 15-20% in farmland where magnesium oxide fertilizer is applied. This can significantly increase income for farmers. Magnesium oxide can improve the nutritional quality of crops, increase the sugar and vitamin content of fruits, and make agricultural products more market competitive. Research shows that the sugar content of fruits and vegetables using magnesium oxide fertilizer increases by an average of 10% and the vitamin C content increases by 15%.
5. Reduce the cost of fertilizer use
Magnesium oxide is relatively inexpensive and can achieve significant results with a small amount of application. Its good soil conditioning and nutrient supply capabilities can reduce the use of other chemical fertilizers, thereby reducing the overall cost of chemical fertilizer use. Economic analysis shows that the total cost of fertilizer can be reduced by about 10-15% in farmland using magnesium oxide fertilizer.
