Alumina Special (AL2O3)
A: Fine Calcined Alumina Powder
It is white powder, uniform grain size, low moisture, stalble chemical performance. Used as raw materials for aluminous refractory, ceramic products, sparking plugs, grinding materials. It is basic material for aluminous refractory and high quality fillers with strong fire-retardantperformance.
B: Low Temperature Alumina
Alumina is white or slightly red powder or ball-shaped particles, insoluble in water and organic solvent, soluble in acidic and alkaline solutions, moisture absorptive in air. It is used as deacidifying-regenerant of transformer oil, purifying agent, catalyst.
C: High Fine Alumina
High fine alumina is white granular powder, high purity, weather stability, corrosion resistance. It is used in producing HF porcelain, ceramic substrate, high hardness device, three sub-sodium lamp fluorescent tube.
D: Calcined Alumina
Calcined Alumina is white powder, good flowability, performance stability, hardly soluble in acid and alkali, excellent sintering property. It used as high quality material for aluminous refractory, sintering coroundum and electric ceramics.
E: Alumina (AL2O3)/Industry grade
Alumina(industry grade) made by slkali-lime sintered, It is white powdered crystal with low assay of Ti, Mn, Zn, Cu, V, Zr, Cr, Li, Pb, B, P, etc. It is used in the production of fused salt eletrorefining aluminium, corundum eramics, refractories and other alumina chemical products
F: Activated alumina(for Hydrogen peroxide)
Activated alumina is white, ball-shaped or roll-shaped, nontoxic, odorless,
Tasteless, insoluble in water and organic solvent, soluble in strong acids and alkalis, It used in hydrogen peroxide, adsorbents.
G: Activated alumina (Defluorination formulations)
Activated alumina (Defluorination formulations) is white or red spherical or cylindrical-shaped micro-particles, after absorbing moisture in air, it does not expand and crack, and keeps its original shape. It is made by scientific deployment high-purity alumina, catalyst. It is adsorptive with F2. It is used in the petrochemical industry, defluorant, deacidification agent, industrial arsenic acid, hydrogen peroxide
H: Activated Alumina (AL2O3)/Desiccant type
Activated alumina(Desiccant type) is white or red spherical or cylindrical-shaped micro-particles, odorless, tasteless, nontoxic. It is big surface area, high compressive strength, hardness, long service life, and through renewable methods used repeatedly. After absorbing moisture in air, it does not expand and crack, and keeps its original shape. It is adsorptive with NOX, F2, As and other gases. It is used in Petrochemical, chemicals, textiles, metals, steel, gas oil cracking, latex, Acryl.
