Alumina balls are spherical alumina particles that are typically used in a variety of industrial applications. They are made by agglomerating fine alumina powder into spherical particles, which can then be sintered to achieve the desired properties.
Alumina Balls Properties
The properties of alumina balls can be tailored to the specific application by controlling the particle size, shape, and surface chemistry.
- High melting point: The melting point of alumina is 2050°C, which makes it a good choice for applications that require high temperatures.
- Good thermal conductivity: Alumina is a good conductor of heat, which makes it useful in applications where heat needs to be transferred efficiently.
- Corrosion resistance: Alumina is resistant to corrosion by most acids and bases.
- Chemical inertness: Alumina is chemically inert, which means that it does not react with other substances.
- Hardness: Alumina is a hard material, which makes it wear-resistant.
- Low density: Alumina has a low density, which makes it lightweight.
Alumina balls are a versatile material with a wide range of applications. They are used in a variety of industrial, biomedical, and other applications.
Alumina Balls Applications
- Furnace linings
Alumina balls are used as furnace linings because they are resistant to high temperatures and corrosion. They are also good insulators, which helps to conserve energy.
- Filtration
Alumina balls are used as filters because they are able to trap small particles. They are used in a variety of filtration applications, such as water filtration and air filtration.
- Adsorbents
lumina balls can be used as adsorbents to remove impurities from liquids or gases. They are used in a variety of applications, such as wastewater treatment and gas purification.
- Lubricants
lumina balls can be used as lubricants because they are hard and smooth. They are used in a variety of applications, such as metalworking and bearings.
- Biomedical applications
lumina balls are used in a variety of biomedical applications, such as bone implants and drug delivery systems. They are biocompatible and can be sterilized, making them ideal for these applications.
Alumina Balls Price
The price of alumina balls varies depending on the size, shape, purity, and surface treatment. In general, the price of alumina balls is higher for smaller particles, higher purity, and more surface treatment.
For example, the price of 1 mm alumina balls with 99.5% purity and no surface treatment is around $10 per kilogram. The price of 0.5 mm alumina balls with 99.9% purity and a hydrophobic surface treatment is around $20 per kilogram.
The factors that affect the price of alumina balls:
- Size: The smaller the particles, the higher the price. This is because smaller particles are more difficult to produce and require more processing.
- Shape: The price of alumina balls is also affected by their shape. Spherical alumina balls are more expensive than irregular-shaped alumina balls. This is because spherical alumina balls have better flowability and are easier to process.
- Purity: The purity of alumina balls also affects their price. Higher purity alumina balls are more expensive because they require more processing to remove impurities.
- Surface treatment: The price of alumina balls can also be affected by the surface treatment. Alumina balls with a surface treatment, such as a hydrophobic coating, are more expensive than untreated alumina balls. This is because surface treatment improves the properties of alumina balls, such as their wettability and corrosion resistance.
