High Alumina Ceramic Balls
Description
Technical Parameters
Products Description
High alumina ceramic balls use 92% and 95% high-purity alumina as the main raw materials. After precise proportioning, high-pressure molding, and ultra-high temperature sintering, they form a compact and uniform internal structure with stable physical and chemical properties. They can remain completely inert in alternating temperatures and complex media environments, without deformation, crushing, or chemical reactions.
Unlike grinding ceramic balls, high alumina ceramic balls focus on filler performance, fluid distribution, and long-term stability. They have ultra-low water absorption, high packing density, and excellent thermal shock resistance, which can adapt to working conditions of high temperature, high pressure, and strong corrosion. They effectively support catalysts, optimize fluid flow, extend equipment lifespan, reduce production downtime and maintenance costs.

Advantages
1. High temperature resistance
They can be used for a long time in high-temperature environments without softening, deformation, or structural damage, and are suitable for the harsh working conditions of industrial reactors.
2. Low water absorption rate
The water absorption rate should be controlled below 0.01% to prevent moisture absorption and crushing. Ensure stable operation of high alumina ceramic balls in humid, gas and liquid mixed environments to avoid affecting catalyst activity.
3. Excellent chemical inertness
They have strong corrosion resistance to acids, bases, and organic solvents. They do not react with raw materials, catalysts, or reaction media, ensuring the purity and stability of the production process.
4. High mechanical strength and resistance to compression
The Mohs hardness is as high as 9, and the packing density is high, which can withstand huge packing pressure and material impact. Will not rupture or shatter under long-term pressure.
5. Excellent thermal shock resistance
They maintain structural integrity under rapid temperature fluctuations (200 ° C to 800 ° C). It will not crack due to temperature changes and is suitable for working environments with frequent temperature adjustments.
Applications
1. Petroleum, chemical, and fertilizer industries
As a catalyst carrier in hydrocracking reactors (20-50mm balls), distillation tower packing, and urea production tower protection beds, it can withstand temperatures up to 450 ° C and pressures up to 150 bar.
2. Smelting, Gas and Environmental Protection
Used for gas scrubbing (SO ₂ removal) in the exhaust gas system of smelters, natural gas dehydration towers, and as a supporting medium for SCR catalysts in power plant emission control (nitrogen oxide reduction>90%).
3. Automobile exhaust treatment
Used as a substrate for automotive exhaust catalytic converters, especially for diesel vehicle systems. High alumina ceramic balls provide stable thermal shock resistance and protect catalytic components during rapid temperature changes.
4. Natural gas and industrial gas processing
Used as a drying and purification filler in natural gas and industrial gas towers. They remove impurities and moisture to ensure the purity of gas products.
5. High temperature reaction equipment
Used as an inert carrier and covering medium in various high-temperature reactors and catalytic devices. They isolate the catalyst from the interior of the equipment, extending the service life of the core components.
Why choose HUAO's high alumina ceramic balls?
1. Strict control of raw materials
We only use high-purity alumina powder with stable composition. Each batch of raw materials undergoes purity and particle size testing to ensure the basic performance of the finished product.
2. Professional sintering process
Adopting high-temperature tunnel kiln sintering technology, precise control of sintering temperature and insulation time ensures complete densification of the spheres and stable batch performance.
3. Total Quality Inspection
Each batch undergoes density, hardness, water absorption, and compressive strength tests. We provide complete testing reports and support third-party testing.
4. Low wear and long service life
The ultra-low wear rate and high mechanical strength reduce medium loss and replacement frequency. They help customers reduce long-term operating costs.
5. Safe packaging for convenient transportation
We use moisture-proof and shockproof packaging (cardboard boxes, wooden boxes, pallets) according to the product size. They are suitable for sea, land, and air transportation to ensure that products arrive intact and undamaged.
