Explore our core catalog items manufactured under strict ISO 9001:2015 quality assurance protocols in Pingxiang, China's world-renowned industrial chemical ceramic hub.
A rigorous economic breakdown of material purities, thermal firing curves, and global spot pricing mechanisms compiled by process engineers and procurement strategists.
In global industrial refining, fertilizer production, and petrochemical synthesis, specifying inert alumina ceramic balls is an exercise in managing chemical resistance against thermal crush failure. As an international manufacturing leader since 2003, Pingxiang Zhongtai Environmental Chemical Packing Co., Ltd. analyzes the core macro-economic drivers shaping wholesale procurement costs. Ceramic ball prices are fundamentally driven by four factors: raw calcined alumina powder pricing, natural gas thermal sintering indexes, isostatic pressing mold tolerances, and quality verification standard adherence (e.g., ASTM D4179 for single pellet crush strength).
| Material Grade | Al₂O₃ Content (%) | Bulk Density (g/cm³) | Crush Strength (kN/particle, 25mm) | Max Operating Temp (°C) | Estimated Wholesale Price (USD / MT) |
|---|---|---|---|---|---|
| Standard Inert Porcelain | 17% – 23% | 1.35 – 1.45 | ≥ 3.5 kN | 1050 °C | $260 – $420 |
| Medium Alumina Support | 23% – 30% | 1.40 – 1.55 | ≥ 4.8 kN | 1150 °C | $380 – $580 |
| High Alumina Media | 68% – 75% | 1.80 – 2.05 | ≥ 8.5 kN | 1380 °C | $750 – $1,150 |
| Refractory Bed Support | 90% – 92% | 2.05 – 2.20 | ≥ 12.0 kN | 1500 °C | $1,100 – $1,550 |
| Super High Purity Inert | 99.0% – 99.5% | 2.15 – 2.30 | ≥ 16.5 kN | 1650 °C | $1,650 – $2,300 |
Engineered ceramic spheres and structured contact media deployed across mission-critical chemical reactors, environmental treatment units, and energy facilities.
Acts as bottom support media and top hold-down layers in hydrotreaters, hydrocrackers, and catalytic reformers. Prevents noble metal catalyst migration, absorbs process hydrodynamic surges, and ensures uniform axial gas-liquid fluid distribution.
Operates in secondary steam reformers and high-temperature water-gas shift reactors. Extreme resistance to chemical leaching of silica (SiO₂ < 0.2%) eliminates downstream heat exchanger fouling and catalyst poisoning across multi-stage synthesis loops.
Combines high chemical stability in aggressive media. Provides acid resistance rating > 99.8% against concentrated hot sulfuric acid, wet chlorine, and nitric acid environments when paired with ceramic Intalox saddles and partition rings.
Paired with cordierite and honeycomb ceramic heat storage media for industrial volatile organic compound (VOC) abatement systems. High volumetric thermal capacity enables over 95% thermal efficiency recovery in harsh chemical exhaust streams.
Serves as heavy-density guard layers protecting 3A, 4A, and 13X molecular sieves in PSA (pressure swing adsorption) drying columns. Dampens pulsation shocks, prevents desiccant dusting, and extends regeneration bed life cycles.
Engineered 92% and 95% wear-resistant alumina grinding cylinders and spheres for ball mills. Delivers minimal self-wear contamination in zircon sand processing, electronic lithium battery slurry preparation, and ceramic glaze manufacturing.
Founded in 2003, Pingxiang Zhongtai Environmental Chemical Packing Co., Ltd. operates from Pingxiang, Jiangxi Province—the historic epicentre of China's industrial ceramics and mass transfer tower packing cluster. This regional synergy provides deep supply chain resilience, allowing us to source raw refined bauxite, specialized sintering aids, and calcined alumina powders within a 50km radius.
Our Factory 4.0 evolution integrates automated isostatic pressing machines, automatic rolling sphere formers, and computer-controlled 120-meter high-temperature natural gas roller kilns. Continuous thermodynamic profiling ensures each batch meets tight dimensional tolerances and zero micro-structural cleavage planes.

Expert answers addressing crushing strengths, thermal shock tolerances, alumina grading criteria, and bulk international logistics.
Pricing is governed by Al₂O₃ content purity (17% to 99.5%), method of ball forming (isostatic pressing vs. manual/machine rolling), bulk density, kiln sintering cycle length, and certified crush strength limits. Custom particle sizes or strict SiO₂ limits (<0.2%) require specialty calcined powders that impact final metric ton costs.
In steam reforming and ammonia synthesis environments containing high partial pressures of steam at temperatures over 1000°C, volatile silicon hydroxides [Si(OH)₄] evaporate from low-purity balls. This silica travels downstream and precipitates onto cooler heat recovery boilers, causing severe fouling. 99% high-purity alumina ceramic balls prevent this hazard.
The standard rule of thumb is that support balls directly under the catalyst should have a diameter roughly twice the catalyst pellet dimension to avoid bed slumping. Typical gradations run in distinct layers: 1/8" (3mm), 1/4" (6mm), 1/2" (13mm), 3/4" (19mm), 1" (25mm), up to 1-1/2" or 2" (50mm) at the bottom support beam grid.
Yes. We furnish comprehensive physical and chemical test reports covering cold crush resistance, chemical composition (ICP-OES / XRF), acid resistance percentage, specific surface area, and bulk density for each proposed batch.
