Introduction
The 92 high-purity alumina balls refer to ceramic balls with an alumina content of no less than 92%. They possess excellent properties such as high strength, high hardness, and high wear resistance. Additionally, they contain trace amounts of silicon dioxide, iron(II,III) oxide, and other impurities.
Performance Features
High hardness: The Mohs hardness can reach 9, second only to diamond, with extremely strong wear resistance. It can maintain good shape and performance even during high-intensity grinding processes.
Good chemical stability: It has excellent high-temperature resistance and corrosion resistance, can withstand high-temperature environments without deformation, and can resist erosion by acids, alkalis and other organic solvents.
High mechanical strength: The compressive strength is relatively high. For example, the 92 high-purity alumina balls with a diameter of 3mm have a compressive strength greater than 0.4kN, which makes them less likely to crack during use and ensures a long service life.
Low water absorption rate: Low water absorption rate, with a dense internal structure, strong resistance to medium penetration corrosion.
Application fields
Petroleum industry: The packing layer used in catalytic cracking, hydrocracking and other devices, which supports and protects the catalyst, and helps to optimize the distribution of gases or liquids.
Chemical industry: Often used as the packing support in tower reactors, capable of withstanding high temperatures, high pressures and chemical corrosion during the reaction process.
Metallurgical industry: Can be used as refractory materials for high-temperature furnaces and kilns, maintaining stable performance in high-temperature environments and resisting erosion from furnace temperatures and slag.
Environmental protection industry: Used as the packing layer in waste gas treatment equipment, effectively removing harmful substances. Due to its good chemical stability, it can be used for a long time in complex waste gas environments.
Price reference: The price varies depending on the purchase quantity. For example, on the Made-in-China platform, the price of 92 high-purity alumina balls for 1-24 tons is $1200 per ton.
Comparison of 92% vs. 23% Alumina Inert Ceramic Balls
| Property | 92% Alumina Balls (Advantages/Disadvantages) | 23% Alumina Balls (Advantages/Disadvantages) |
| Cost | Disadvantage: Higher initial cost. | Advantage: Low cost. |
| Hardness & Wear Resistance | Advantage: Excellent, very low abrasion. | Disadvantage: Fair, higher wear. |
| Crushing Strength | Advantage: Very high, for high pressure. | Disadvantage: Moderate, may break. |
| Chemical Inertness | Advantage: Excellent resistance. | Disadvantage: Good, but inferior. |
| Temperature Resistance | Advantage: Excellent (up to ~1600°C). | Disadvantage: Good (up to ~1200°C). |
| Application | Advantage: Severe service, high purity. | Advantage: Mild duty, covering layer. |
In short: Choose 92% Alumina for performance in harsh conditions. Choose 23% Alumina for cost-effectiveness in mild conditions.
