High Temperature Calcined Alumina Powder
Description
Technical Parameters
Products Description
High temperature calcined alumina powder is a white loose powder, insoluble in water and most acids, odorless, non-toxic, and pollution-free. It uses industrial aluminum hydroxide as the core raw material, adds supporting mineralizers, and undergoes high-temperature calcination in a rotary kiln. This production process endows it with more stable physical and chemical indicators, resulting in strong chemical stability, high purity, and high specific gravity.
Unlike ordinary alumina powder, high-temperature calcined alumina powder has a more complete crystal structure, higher conversion rate, and better grinding performance. Its chemical composition, true density, particle size, shrinkage rate, etc. are strictly controlled, and various indicators are coordinated with each other to ensure the stability of the finished product. It is not only the basic raw material for the production of aluminum metal, but also an irreplaceable core material for high-temperature refractory products, precision ceramic parts, and high-end surface treatment.
Advantage
1. Low shrinkage and high temperature stability
After being fully calcined at high temperatures, its shrinkage rate is extremely low, and it can maintain chemical stability at ultra-high temperatures without decomposition, deformation, or reaction with acids, bases, or metal substances.
2. Easy to grind
High temperature calcined aluminum powder has moderate hardness, uniform internal structure, and is easier to grind into the target particle size. It can reduce the wear of grinding equipment and energy consumption during the production process, and improve overall processing efficiency.
3. High density
The products made from it have better wear resistance and impact resistance, and a longer service life.
4. Insulation performance
It has excellent electrical insulation performance and is non-conductive at high temperatures, making it very suitable for manufacturing high-temperature insulation pipes, insulation bricks, and electrical insulation components.
5. White without impurities
The powder is pure white with low impurity content and no visible impurities.
Application
1. Advanced refractory materials
It is the core raw material for manufacturing high-temperature insulation bricks, fireproof pipes, refractory crucibles, and heat-resistant laboratory instruments. It can withstand ultra-high temperatures and is widely used in metallurgy, chemical engineering, and thermal engineering fields.
2. Fine ceramics
Used for producing high-performance ceramic parts, ceramic substrates, and sealing components. Its low shrinkage and high stability ensure the dimensional accuracy and service life of ceramic products.
3. Aluminum metal production
As the basic raw material for industrial aluminum production, it provides high-quality raw material support for the aluminum smelting industry.
