High Purity Reactive Alumina Powder Custom Particle Size For Refractory Castables
Product Description:
HUAO HA500 Reactive Alumina Micro-Powder is an ultra-fine, high-purity alpha alumina engineered specifically for high-performance refractories and advanced ceramics. Featuring low impurity levels, a sharp singlet particle size distribution (D50 = 0.5 um), and high BET surface area, it optimizes particle packing density and minimizes mixing water demand.In critical applications such as steel ladle linings, iron runners, purging plugs, seating blocks, corundum self-flowing castables, and spray coatings, HA500 accelerates solid-state sintering. This structural densification significantly enhances mechanical strength, thermal shock endurance, and resistance against severe molten slag erosion in extreme high-temperature environments.
