Порошок оксида алюминия белый

white aluminium oxide powder1. Description:White Aluminium Oxide, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.2.chemical compositions and physical properties:White Aluminium Oxide FunctionModel NumberMain Chemical Composition (%)Al2O3SiO2Na2OFe2O3Grinding and sandblastingJIS#10-JIS#8099.55min0.04max0.22max0.04maxJIS#90-JIS#18099.54min0.04max0.25max0.04maxJIS#220-JIS#24099.53min0.04max0.25max0.04maxPolishingJIS#280-JIS#70099.35min0.10max0.26max0.05maxJIS#800-JIS#150099.25min0.14max0.30max0.06maxJIS#200099.20min0.15max0.32max0.07maxJIS#2500-JIS#400099.00min0.15max0.35max0.08maxRefractory material0-1,1-3,3-5,5-8mm99.60min0.04max0.20max0.04max180,200,240,280,320F99.00min0.05max0.30max0.04max Item Property Color White Bulk density 1.75-1.95g/cm3 Grain density 3.90g/cm3 Morse hardness 9 Melting point 2250°C Refractoriness 1850°C 3.Usage: JIS#10-JIS#240 (1)It can make the abrasive tool to grind the great hardness material, such as the high speed steel, stainless steel and high carbon steel. (2)It also usually used for sandblasting, such as precious metal, the gold, crystal, the glass andcowboy wear. JIS#280-JIS#4000 (1)Itcan be used in grinding and polishing the gold, silver jewellery, the eye glass, bearing andany kind of precision instrument. (2)It can be used in manufacturing the superfinishing stone. (3)It can be used in making the superior refractory products. 0-1,1-3,3-5,5-8mm and 180,200,240,280,320F It is usually used for refractory material. 4.About usHenan Sicheng Co., Ltd, founded in 1999,is specialized in White Fused Alumina, Brown Fused Alumina, Mullite and other related products.
