Product Name: Al2O3 Alumina Electrode Assemblies Spark Tube Ceramic Ignitor Model NO.: GY-DHQ01 Shape: Tubular Form: Heating Wire Material: Alumina Ceramic Type: Far Outside Heating Tube Certification: ISO9001 Item No.: Gy-Dhq01 Alumina Content: 95% Al2O3 Density: 3.6~3.9g/cm3 Thermal Conductivity (at R.T.): 18-25 W/(M.K) Max Working Temperature: 1500 Size: Customized Transport Package: Carton/Wooden Case Specification: customized Origin: Jiangsu, China Product Description AL2O3 Alumina Electrode Assemblies Spark Tube Ceramic IgnitorAluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.Unit95% AL2O399%AL2O3ZrO2GP-Si3N4Densityg/cm³3.653.885.953.22Color-WhiteIvoryWhiteGrayWater Absorption%0000Young's ModulusGpa280350205295Vickers HardnessGpa14201218-20Flexural Strength ( at R.T. )Mpa280300900650Compressive Strength ( at R.T. )Mpa2000250022002200Thermal Conductivity ( at R.T. )W/(m.K)18-25302225Thermal Shock Resistance△t (ºC )220180-200280-350450-650Max Working Temperature ( at R.T.)ºC150017008501200Volume Resistivity ( at R.T. )Ω.cm>10^15>10^14>10^12>10^14Dielectric Constant ( 1MHz at R..T.)-9.509.80268.20Dielectric StrengthkV/mm1622-16* Features:1).
