Spherical Aluminum oxide Powder – Properties and Applications |


Aluminium oxide in spheres

High-temperature melt spraying produces high sphericity aluminum oxide with high amounts of a-phase. The material has superior properties when it is used in fillers for plastics, rubber, and ceramics.


Spherical Al oxide powder Properties


1. The highest filling
Spherical aluminum dioxide has high sphericity with a wide distribution of particle size. You can use it to replace high-density plastics and rubber, as well as create a mix with good viscosity.


2. Very high thermal conductivity


A mixture of spherical and crystalline aluminum oxides can be made with very high levels of density. This is in contrast to crystalline silica powder.


3. Very low wear


The appearance of spherical aluminiu oxide, which is also spherical in form, reduces the amount of wear on equipment like kneaders, mold machines, and molds. It can even extend the equipment’s service life.


Aluminum powder applications


1. As a ceramic material


For the production high-quality ceramic products, sphere aluminum oxide exhibits excellent compression molding properties and sintering capabilities.


2. It is used as a grinding or polishing material


You can prevent scratches by using spherical aloo oxide as your polishing abrasive.


3. It is used in the petrochemical sector


Higher requirements for the size distribution and structure of the aluminum dioxide carrier are being made in the petrochemical sector. You can adjust the size of the particles to regulate the distribution and size of the formed catalyst carrier particle.


4. Catalyst


Spherical aluminum oxide can be used as a direct catalyst to reduce abrasion. It also increases the life expectancy of the catalyst. This helps lower the production cost.


5. For surface protection coatings


Aluminum oxide powder in spheres can be sprayed onto metals, plastics, and other materials. The powder can be used to improve the surface hardness of metals, their corrosion resistance, wear resistance, fire resistance, as well protection for machinery, knives and chemical pipelines.


6. For luminescent material


High packing density in spheres of aluminum oxide powder will reduce scattering and transmit light more effectively.


7. This is used in the electronic industry


Because of its outstanding electrical and thermal properties, spherical aluminiu oxide is widely used for semiconductor electronic packaging.
