High Purity 99.99% Nano Aluminium Oxide Al2O3 Powder Used as Polishing Materials

Calcined alumina powder High temperature calcined alpha alumina powder is produced by aluminum hydroxide powder or industrial alumina powder as raw material, with 1450 ºC high temperature tunnel kiln calcining process, adding special additives reduce the impurity content, improve the alpha conversion rate, control the crystal shape, particle calcined under enough heat preservation time, and the micro powder is the use of high alumina ball mill grinding classification.Features: high purity, high whiteness, than really important, good thermal stability, uniform particle size distribution and liquidity is good wait for a characteristic.Application: widely used in ceramics, electrical porcelain, refractories, spark plugs, brake pads, high insulation, high purityrefractory fiber, high-grade castable, grinding polishing, artificial stone, etc.  Item Al2O3≥(%)SiO2≤(%)Fe2O3≤(%)Na2O≤(%)α- Αl2O3≥(%)O.I≤(%)True Density(g/cm3)ParticleSize(D50μm)ATY-100A99.50.030.020.2940.103.9483-98ATY-100B99.30.040.030.3930.103.9383-98Particle Size(D50μm):  it can be adjusted appropriately according to your needsLow sodium calcined alumina powderFeatures: Low sodium calcined aluminum oxide has the advantages of high alfa phase conversion, high hardness, low sodium content, high purity, stable thermal performance, low shrinkage, high porcelain density, good electrical insulation, high thermal conductivity.Especially suitable for the production of over 92% corundum and ceramic products, especially 95% alumina porcelain, widely used in water valve plate, seal ring, ceramic materials, textile machinery and other wear-resistant ceramics, low sodium high temperature aluminum oxide is also used in spark plug, vacuum tube shell and other electronic ceramics with high strength and wear resistance.Application: 1. Electronic vacuum shell, spark plug and other electronic ceramics.Such as Copper Clad Laminate(CCL), Epoxy Moulding Compound(EMC) 2. Paper machinery, seal ring, textile machinery and other wear-resistant ceramics.3. Alumina crucible, porcelain tube and other high-temperature materials.4.
