What Are The Upmarket Applications for Ultra-fine Alumina Powder?

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. There are effects, quantum effects, macroscopic quant tunneling effects, as well as effects, quantum effects, which have outstanding properties. These include high strength, high hardness. They are widely used today in the aerospace lighting source device, precision ceramics as well as bioceramics.
1. Ceramic materials and mixed materials
The inclusion of ultrafine aluminum powder to ceramics may increase their strength and decrease the temperature at which they sinter. 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-2O3 ultra-fine Composite Material is the best-known. It has an increased flexural force of 300-400 MPa and 1 GPa when used in single-phase Silicon carbide ceramics. Furthermore, its fracture toughness can also be improved by 40%.
Also, dispersion strengthening and additives can be achieved with ultrafine alumina. If cast iron laps have been 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 particles on the surface metals, ceramics or plastics. The purpose of this new material, which is ultra-thin and translucent, is to increase surface hardness, resistance, wear resistance and corrosion resistance. The material is suitable for protecting machinery, tools, chemicals pipes and similar surfaces.
The ultra-fine cemented ceramic coating tool, which combines all the strengths of ceramic material and cement carbide, has the toughness and durability of the cemented material. Additionally, it can reduce the number of tools that are uncoated. Processing efficiency can be dramatically improved as it’s multiplied several times.
3. Catalyst und its transporter:
Ultra-fine Alignment has excellent pore size distribution, high surface area and 60-400m2/g surface area. Also, it is easy to form mismatching or under-oxygen bonds. With the increase in the particle size, the surface will become smoother. It is also a good catalyst, helping to increase the surface contact of chemical reactions and preventing atomic steps from being missed. HDS activity of Co-Mo’s ultrafine, alumina particle-loaded CoMo catalyst exceeds that of common CoMo. 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 environments. The pores in porous ceramic allow for the growth of new tissue. They also bond well with other body tissues. Because of this, it is widely used in clinics. This has allowed for the production and use of artificial bones, root implants, splints, fractured, and other internal fixation device. It is also capable of performing alveolar and maxillofacial ridge expansion, as well as reconstructions. You can make repairs or changes to your facial features.
Research at the moment is on soft tissues materials such artificial airways as well bioceramics materials that replicate biological functions and artificial Intelligence.
5, Semiconductor material:
Ultra-fine powdered alumina has a high interface and surface area, making it very sensitive for moisture from the environment. 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. It has fast response times, high reliability, high sensitive, good resistance to gas erosion, pollution and can even be maintained in a dusty environment. Perfect for wet and humid sensors, this sensor has excellent detection accuracy.
The most common sub-material material is ultra-fine aluminium. It has the following characteristics: good electrical insulation; chemical durability; heat resistance; strong radiation resistance; high dielectric constant; uniform surface; low cost. Many sub-materials for devices and low-cost LSIs can be found in microelectronics.
6, optical materials:
Nanoscale-sized alumina can absorb ultraviolet light. When excited by certain wavelengths, light waves are produced that are related to 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. To reduce lamp light degradation and maximize lamp yield, you can add ultrafine Al2O3 granules to compact fluorescent lights.
An extra layer of nonhazardous resin is added to the surface of the Alumina Granules.
The reason is that ultrafine Alumina Powder has superior properties than ordinary particles. The world has recently discovered that ultrafine alumina is a novel material. One example.
