HUAO Reactive Alumina is a high-purity, white alpha alumina engineered for high-performance refractory applications. It serves as a vital matrix component in steel ladle castables, iron ditch castables, breathable bricks, block bricks, corundum self-flowing castables, and spray coatings.By optimizing particle packing and reducing water demand, it enhances matrix fluidity and accelerates solid-state sintering. This structural densification delivers exceptional mechanical strength, thermal shock endurance, and severe slag erosion resistance in extreme high-temperature operating environments.

1.Q: What is the packaging for Reactive Alumina?
A: It can be packed in 25kg bags, 1250kg big bags, or Jumbo (BB) bags according to the customer's requirement.
2.Q: What is the accepted payment method for Reactive Alumina?
A: We accept 100% payment in advance or 30% T/T in advance with the balance payment before delivery.
3.Q: What are the main applications of Reactive Alumina?
A: Reactive Alumina is mainly used as a high-performance matrix filler in refractory castables, steel ladle linings, blast furnace iron runners, porous purging plugs, seating blocks, and advanced ceramic products.
4.Q: How does Reactive Alumina improve refractory performance?
A: It optimizes particle packing density, lowers mixing water demand, improves matrix fluidity, and promotes solid-state sintering during firing. This results in higher mechanical strength, thermal shock resistance, and slag erosion resistance.
5.Q: What is the shelf life and storage requirement for Reactive Alumina?
A: The shelf life is typically 2 years when stored in a cool, dry place in its original sealed packaging to prevent moisture absorption and agglomeration.
