Product Description Product Description A ceramic crucible is a heat - resistant container. It's usually made from materials like clay, porcelain, or other ceramic substances. These crucibles can withstand high temperatures, which makes them ideal for use in processes such as melting metals, conducting chemical reactions that require heating, and in laboratory experiments such as sample preparation for analysis. They are chemically stable to a certain extent and help to contain substances during heating without reacting with them easily.Detailed Photos Product ParametersTechnical DataCeramic characteristics Item99% Ceramic 95% Ceramiczirconia Main contentAL2O3>=99%AL2O3>=95%ZrO2>=94%physical propertyDensity3.853.65.9Water absorption %000Sintering temperature 1690oC1670oC1650oCMaterial propertyHardness HV170016001400Flexural strength 4pt>3500>2900>11000Compressive strength Kgf/cm2300002500025000Thermodynamic propertyMaximum working temperature1500oC1400oC1600oCCoefficient of thermal expansion87.81010-6/oC0-1000oCHeat shock force T(oC)200220350Thermal conductivity W/m.k31223Electrical characteristicVolume resistivity Ω.cm>1012>1012>1012Insulation breaking strength KT/m181615Dielectric constant 1MHZ(E)9.2-10.59.0-1012.5ApplicationsCompany Profile
