99.7% Al2O3 Alumina Ceramic Corundum Crucible, Alumina Boat¹

Product Description Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Alumina Tubes are available in different diameters and lengths. Feature of alumina crucible:high purity: Al2O3>99.5% well chemical corrosion resistanceGood temperature resistance, long time used at 1600oC, short-term at 1800oC.Good thermal shock resistance, not easy to burstSlip casting of high densityShapes and capacity: We can make from 5ml to 6000ml. Our standard ones are, 10ml, 20ml, 30ml, 50ml, 100ml, 130ml, 150ml, 200ml, 1000ml, 2000ml etc Product classification:High formCylindrical cruciblesRectangularMain performance of high form alumina crucible Producehigh form alumina crucible    Chemical compositionAl2O3≥99R2O≤0.2Fe2O3≤0.1SiO2≤0.2 Volume density(g/cm2)≥3.80                          Gas hole rate(%)<1Flexural strength(Mpa)>350Compressive strength(Mpa)>12000   ∑(1MHz)2  Max use temperarure(oC)1800 SpecificationApplicationSize ( mm)Capacity(cc)Firing color powder, fluorescent powder, rare earth materials, metal materials, baking, high, low NTC ceramic capacitor, PTC piezoelectric ceramic, lithium cobalt oxide, optimum vessel of LiMn2O4 powder Out diameterheightWall thickness15~300 15~300   >25~10000Main peroformance of cylindrical alumina crucible ProduceSquare alumina crucible    Chemical compositionAl2O3≥99R2O≤0.2Fe2O3≤0.1SiO2≤0.2 Volume density(g/cm2)≥3.80                          Gas hole rate(%)<1Flexural strength(Mpa)>350Compressive strength(Mpa)>12000   ∑(1MHz)2  Max use temperarure(oC)1800 SpecificationApplicationSize ( mm)Capacity(cc)Firing color powder, fluorescent powder, rare earth materials, metal materials, baking, high, low NTC ceramic capacitor, PTC piezoelectric ceramic, lithium cobalt oxide, optimum vessel of LiMn2O4 powder Out diameterheightWall thickness20~200 20~300   >25~10000Main performance of rectangular alumina crucible ProduceSquare alumina crucible    Chemical compositionAl2O3≥99R2O≤0.2Fe2O3≤0.1SiO2≤0.2 Volume density(g/cm2)≥3.80                          Gas hole rate(%)<1Flexural strength(Mpa)>350Compressive strength(Mpa)>12000   ∑(1MHz)2  Max use temperarure(oC)1800 SpecificationApplicationSize ( mm)Capacity(cc)Firing color powder, fluorescent powder, rare earth materials, metal materials, baking, high, low NTC ceramic capacitor, PTC piezoelectric ceramic, lithium cobalt oxide, optimum vessel of LiMn2O4 powder lengthwidthheightWall thickness60~20030~15015~190   >25~5000Application Applicable to all kinds of metal, non-metallic laboratory sample analysis and the molten material.High purity alumina crucibles and boats are working as high temperature containers, widely used in furnaces and kiln.Shipment Methods: Sea or Air transportation, train or express Payment Methods:    1) L/C ; 2) T/T ; 3) Paypal ; 4) Money Gram ; 5) Western UnionAbout us1. Our company is a high & new technology enterprise specially engaged in developing, manufacturing and selling alumina tubes and crucibles.2.
