Alumina powder ultrafine is an essential material for modern industry. Surface electronic structure and crystal structure of ultrafine-grained alumina sand have been modified, creating surface effects and sizes not seen in microbes. It exhibits effects, quantum effects, macroscopic quantum tunneling effects, as well its excellent properties of high strength, high hardness and high corrosion resistance. They are widely used today in the aerospace lighting source device, precision ceramics as well as bioceramics.
1. Ceramic materials, and composite materials
The inclusion of ultrafine aluminum powder to ceramics may increase their strength and lower their melting point. Alumina powder that is ultra-plastic can overcome the limits of low temperature applications. It can be used in many ways.
It is possible to synthesize new types of composite ceramic materials with specific functions using ultrafine alumina. SiC-Al2O3 Ultra-Fine Composite Material is the most important. This material can increase its flexibility from 300-400 MPa up to 1 GPa single-phase silicone carbide ceramics. Furthermore, its fracture toughness has also been increased by more that 40%.
Also, dispersion strengthening and additives can be achieved with ultrafine alumina. If cast iron laps need to be cast, then ultra-fine Alumina Powder can be used as metamorphic Nucleation. It is possible to improve the wear resistance by up to tenfold.
2, Surface protective layer material:
An ultra thin transparent material that is coated with ultra fine alumina powders on the surfaces of metals. The material is suitable for protecting machinery, tools, chemicals pipes, and similar surfaces.
One is the ultrafine alumina clay coating tool. It has all the characteristics of ceramic material and cemented-carbide material. Processing efficiency can be dramatically improved as it’s multiplied several times.
3. Catalyst und its transporter:
Ultra-fine Alignment has excellent pore distribution, high pore volume and surface area up to 60-40 m2/g. Surface atomic coordination is also a key feature. There are many mismatching or under-oxygen bonds along the surface. Also, the particle size decreases, making the surface more smooth. It is also a good catalyst, since it can form an uneven atomic step and increases the contact surface for the chemical reaction. HDS activity of Co’Mo is significantly higher than of common Co-Mo. It has high HDS activity.
The main application of catalyst and carrier is γ-Al2O3, which is widely used in automobile exhaust gas purification, catalytic combustion, hydrodesulfurization, petroleum refining, and polymer synthesis.
4. Bio- and Medical Materials:
The ultrafine, alumina bioceramic doesn’t significantly corrode when exposed to physiological conditions and is structurally compatible. It allows new tissue to form in the pores. Because of this, it is widely used in clinics. This has allowed for the production and use of artificial bones, root implants, splints, joint restorations, and other internal fixation device. It is also capable of performing alveolar and maxillofacial ridge expansions. You can make repairs or changes to your facial features.
At the moment, researchers are focusing their attention on soft tissues such as artificial lungs and bioceramics to simulate artificial intelligence.
5, Semiconductor material:
Ultra-fine Alumina Powder has very high surface area and interface. This powder is highly sensitive to environmental moisture. Rapid changes in ambient temperatures can lead to significant differences in electron transport or surface ion valence. Within the humidity range from 30-80%, the ultrafine alumina AC Impedance changes linearly. This is due to fast response, high reliability and high sensitive. Also, this AC will not change in the presence of other pollutants or gas erosion. Perfect for wet and humid sensors, this sensor has excellent detection accuracy.
The most common sub-material material is ultra-fine aluminium. It has electrical insulation properties, good chemical durability, resistance to heat, radiation, strong radiation resistances, high dielectric constants, uniform surface and low cost. Many sub-materials for devices and the LSIs used in microelectronics electronics, information, and other industries.
6, optical materials:
Nanoscale-sized alumina can absorb ultraviolet light. When excited by certain wavelengths, light waves are produced that correspond to specific particle sizes. To improve tube life, it can be used in protective films for the phosphor layers of compact fluorescent lamps.
An excellent anti-ultraviolet absorber is ultrafine alumina. Ultra-fine Al2O3 can be added to compact fluorescent lamps to decrease lamp light decay. This will also improve lamp yield.
The aluminagranules’ surface is covered with non-hazardous polymer, which can also be used in cosmetics and sunscreens.
The reason is that ultrafine Alumina Powder has superior mechanical, electrical and chemical properties to traditional particles. The world has recently discovered that ultrafine alumina is a novel material. One example.
