Product Description Product DescriptionMullite alumina ceramic crucibleMullite alumina ceramic crucible is made of mullite. it is mainly used for sintering electronic and magnetic material.Many electronic or magnetic materials have chemical reactions with the ceramic sagger surface during sintering. The saggers used in sintering of various magnetic materials produced by our company are all reasonably selected materials, formed under high pressure and sintered at high temperature, which can play a good insulating role. In addition, the surface of saggar has excellent corrosion resistance by various spraying methods, such as zirconia and high purity alumina.Crucibles for melting steel features:1) High density2) Good thermal stability and distortion resistance at high temperature.3) High mechanical strength at high temperature.4) Excellent thermal shock resistance.5) High thermal conductivity.6) Perfect oxidating resistance.7) Excellent corrosion resistance against chemicals at high temperature.8) High abrasion resistance.9) Long service lifeItemTesting Condition95% AL2O399% AL2O399.7% AL2O3Physical propertiesDensityg/cm3 >3.63.893.96Moisture absorption% 000Mechanical propertiesROHS Hardness ≥85≥89≥89Flexural strengthpsiX10320oC358550550Compressive strengthpsiX10320oC2068(300)2600(377)2600(377)Fracture toughnessMpa.m3/2K(l c)4.35.66.0Thermal propertiesMaximum use temperatureoC 145016001650Thermal expansion coefficient1X10-6/oC(25-1000oC)7.67.98.2Thermal shock resistanceoCTc250200200Thermal conductivityw/mok20oC163030.4Electrical propertiesVolume resistivityOhm/cm2100oC>1013>1014>1014Dielectric breakdown strengthKV/mm 8.7(220)8.7(220)8.7(220)Dielectric constant(E)1MHz25oC99.79.Q1 : How can you control your quality?A1 : For each production processing, we have complete QC system for the chemical composition and Physical properties.
