With the rapid development of science and technology, people’s requirements for the quality of life are getting higher and higher. In this era of focusing on health and environmental protection, a new material – nano-magnesium oxide (VK-Mg30), is gradually being favored by people.
1. Safety and environmental protection
Nano magnesium oxide has very high safety and environmental protection. As a non-toxic and harmless material, compared with traditional magnesium oxide materials, nano magnesium oxide has higher strength and durability, and also has better corrosion resistance and wear resistance, and can be used in various Long-term use in harsh environments.
2. Strong adsorption capacity
Nano-magnesium oxide has a very strong adsorption capacity and can effectively adsorb harmful substances in indoor air. At the same time, it can also absorb moisture, increase indoor humidity, and improve people’s living environment.
3. Easy to process
Nano-magnesium oxide has good plasticity and processability, and can be easily processed by mechanical processing or chemical methods to meet the needs of different fields. For example, it can be made into adsorbents of various shapes to remove harmful substances in indoor air; it can also be made into efficient photocatalysts to purify indoor environments.
4. Wide range of uses
The application fields of nano-magnesia are very wide, and can be used in many fields such as building materials, catalysts, fireproof materials, and rubber. For example, in the field of construction, nano-magnesium oxide can be used to prepare high-performance concrete and architectural coatings; in the field of catalysts, it can be used to prepare efficient photocatalysts; in the field of fireproof materials, it can be used to prepare efficient fireproof Coatings; in the field of rubber, it can be used to prepare high-performance rubber, etc.
Nano magnesium oxide (VK-Mg30) is a fairly common basic oxide. Since the melting point of magnesium oxide is as high as 2800°C, it has some special and excellent properties, so it can be included in the field of advanced ceramics. In terms of application, it can be divided into direct sintering into ceramics and use as a sintering aid for other ceramics.
1. Direct sintering into ceramics Nano-magnesia (VK-Mg50) is an excellent ceramic raw material. Because of its good heat resistance and strong corrosion resistance to alkaline metal solutions, magnesia ceramics are often suitable for In high temperature environment. It can be used as a crucible for smelting metals. It is also suitable for smelting high-purity uranium and thorium in the atomic energy industry. It can also be used as a thermocouple protection sleeve. And because it has the property of allowing electromagnetic waves to pass through, it can be used as a radome and a projection window material for infrared radiation. At the same time, it is also a raw material for piezoelectric, superconducting materials, etc., and is environmentally friendly and has good lead corrosion resistance. It can also be used as a ceramic sintering carrier, especially for the sintering protection of ceramic products with corrosive and volatile substances at high temperatures such as β-Al2O3.
2. Used as a sintering aid for other ceramics In addition, nano-magnesia (VK-Mg30) can also be added in the preparation process of other ceramics, which can reduce the glass transition temperature, reduce the sintering temperature, and improve The optical and mechanical properties of ceramics help us obtain higher quality ceramic materials.
For example, silicon nitride ceramics have become one of the most promising high-temperature structural materials due to their excellent high-temperature strength, thermal shock resistance, and chemical stability, but their strong covalent bonds and low diffusion coefficients make them difficult to sinter densification. However, the addition of magnesium oxide can react with silicon dioxide on the surface of silicon nitride powder to form a silicate liquid phase during the sintering process, thereby effectively promoting the sintering of silicon nitride ceramics. At present, MgO-Y2O3 composite sintering aids are generally used to realize the normal pressure sintering of silicon nitride ceramics.
In summary, nano-magnesia (VK-Mg30) plays a vital role in the field of ceramics. It can be used as a basic material and an additive to improve the performance and function of ceramics, thereby promoting the progress and development of the ceramic industry.
