Product Desciption
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.
Low sodium calcined alumina powder
Features: 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. High frequency insulating porcelain, LCD substrate glass, ceramic glaze, etc
Calcined AluminaPowder for Ceramic Whitening Agent
This product has small original crystal and good activity. It is widely used in building ceramic floor tiles and ceramic glaze.
Product performance: this product is white powder, whiteness is good, particle size is even, original grain size is small, sintering activity is high.Insoluble in water, insoluble in acid, alkali solution.
Main use:ceramic whitening agent, polishing brick blank body glaze whitening, internal wall tiles, stone and other ceramic materials , because of its and zirconium silicate similar refractive index, can replace zirconium silicate used
Calcined alumina special use for ceramic
USES: various electronic ceramics, high aluminum refractories, unshaped refractories (high aluminum castable), high temperature resistant porcelain, wear-resistant porcelain, electronic substrate, high aluminum ceramics, roller, etc.
Calcined Alumina for refractory material
Features: high temperature alumina is specially produced for refractory enterprises, with high conversion, high fluidity, good dispersibility, uniform particle size and so on. High temperature alumina powder is especially suitable for refractory materials.
Application: Widely used in high aluminum refractory, high aluminum refractory fireball, corundum brick, grinding and polishing, refractory brick, alumina ceramic, etc.
Calcined Alumina for Grinding and Polishing
There are low sodium, medium sodium, ordinary active calcined alumina, mainly used for all kinds of products, substrates, metal polishing and so on, but also for aluminum-based refractory, industrial ceramics, inert catalyst raw materials.
Features: white powder or fine sand, with special crystal structure, uniform powder, suitable oil absorption rate, low impurity, high melting point, moderate hardness, strong self-sharpness, insoluble in water, insoluble in acid and alkali solution.
Application: widely used in grinding, stainless steel and other metal, substrate, jewelry, jade, stone and other polishing industry.
