Inert Alumina Ceramic Balls
Used as catalyst cover or supporting materials in various reactors ortowers.
High mechanical strength
High resistance to corrosion (anti-acid ≥ 98%,anti-alkali≥ 95%)
Strong thermal stability and chemical stability (refractoriness ≥ 1700 °C)
Activated Alumina Ceramic Balls
Used as adsorbent, desiccant and catalyst carrier in petroleum, fertilizer and gas separation industries.
High surface-area-to-weight ratio
Strong absorption capacity(≥50%)
High mechanical strength and thermal stability
Perforated Ceramic Balls
Developed on the basis of inert ceramic ball. It increases surface area and improves porosity as well as material dispersion rate while decreasing resistance due to the perforated holes on the ball body.
Used as thermal storage packing in metallurgical furnace in iron and steel industry, also used in heat accumulator for air separation
High chemical stability
Strong thermal shock resistance
Superior thermal conductivity and thermal capacity (≥1000J/kg.k)
High abrasion resistance and long service time.
Zirconia Oxide Balls
Used as bearings in jigs, gauges, valves, high-grade bicycle parts, automotive parts, machine components, etc.
High strength and toughness(Bending strength: 800-1000 Mpa; Fracture toughness: 6-10 Mpa.M1/2; Vickers Hardness: 12-13 Gpa)
High abrasion and corrosion resistance
Low coefficient of thermal expansion
Superior load bearing capability
High grinding efficiency and long service time.
Silicon Nitride Balls
mostly used in high-endurance, very low lubrication and extreme temperature applications, such as space satellites, turbo-molecular pumps, car engine parts, hybrid bearings and metal working, etc.
Excellent corrosion resistance
Lower Thermal Expansion
high fracture toughness and high strength
Superior Surface Finish
