Product Name: Aluminum Oxide Ceramic Square Crucible Boat Model NO.: yx706 Type: Wear Resistant Ceramic Material: 99.3%-99.7% Alumina Application: metallurgical Machinery, Mining Machine, Thermal Power Plant Standard: DIN Certificates: DIN43724/DIN43725/DIN40680 Market: University and Laboratory Process: Casting Sample: Free Color: White Stock: Full Stock Trademark: Yunxing Transport Package: Wooden Box/Carton Specification: custom size Origin: China HS Code: 8547100000 Product Description Aluminum Oxide Ceramic Square Crucible BoatAlumina Ceramic Crucible is mainly made of alumina. It is fired at high temperature with a special formula. It is a refractory with high fire resistance. It can withstand temperatures of 1800 degrees Celsius and high temperature resistance. It is usually used for smelting precious metals, nickel And other metals, with excellent chemical resistance and high temperature resistance.All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680We only make high purity alumina ceramics1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.3. Alumina is a refractory material, the higher the purity, the better the refractory effect4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ºC ~ 1800 ºC.5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.6. High purity alumina has good hardness and good wear resistance.7. High purity alumina products have a longer service life.Composition tableNAMEConTENT(%)Al2O399-99.3(99.5)SiO20.3-0.5CaO+MgO0.2-0.3K2O+Na2O0.2-0.35Fe2O3<0.1OTHER<0.05Alumina ceramic performance indexNO.PropertyUnitAlumina1Al2O3%>99.32SiO2%-3Densityg/cm33.884Water absorption%0.015Cold compressive strengthMPa350620ºC leakage ratesTorr/L.sec<10-117Twisting in high temperaturemm0.2 allowed in 1600ºC8Bonding in high temperaturenot bonded in 1600ºC920-1000ºCcoefficientofthermalexpansionmm.10-6/ºC.m8.210Thermal conductivityW/m.k2511Electric insulation strengthKV/mm201220ºCdirect currentinsulation resistanceOhm/cm101413High-temperatureinsulation resistance1000ºC MΩ≥0.081300ºC MΩ≥0.0214Thermal shock resistance4 times not cracked in 1550ºC15Maximum working temperatureºC1800Other dimensions, price reference tableNUMBERL*W*H*WT(MM)SHAPEPRICE($)130*20*15*δ2Rectangle0.87245*13/11*9Boat shape with ears0.87348*50/10Trapezoid5.8450*10*10*δ2Rectangle0.87580*50*7*δ1.5Rectangle1.74680*55*15*δ2.5Rectangle2.18784*13/11*8Boat shape with ears0.888100*10*10*δ2Rectangle1.169100*20*20*δ2Rectangle1.7510100*30*30*δ1.5Rectangle3.0511100*40*18*δ2Rectangle2.3412100*50*30*δ4Rectangle6.7713105*22*14*δ2Rectangle2.3314184*123*62*δ5Rectangle34.7815200*100*50*δ2Rectangle26.1116300*36*18*δ3Rectangle2017300*45/30*20*δ2Trapezoid11.75Our factoryJinzhou Yunxing Industrial Ceramics Co., Ltd. was established in 2000, mainly producing various types of tubular ceramic products and various industrial parts with alumina content above 99.3%.
