Product Description Ceramic to metal seals are hermetic joints created by fusing ceramic components to metal substrates using a variety of joining techniques. These seals are renowned for their exceptional heat resistance, chemical stability, and mechanical durability. They're able to withstand extreme temperatures and harsh environments, making them ideal for use in high-performance applications.Brazing Technology is a crucial aspect of the manufacturing process of ceramic to metal seals. Brazing involves the use of a filler metal, which has a lower melting point than the base materials, to bond the ceramic and metal components together. This process creates a strong, reliable joint that maintains the integrity of both materials.MaterialAlumina/BeO/AlNCoating LayerMo/MnThickness:8-30μmPlated LayerNickel, Copper, Gold, etc. Thickness: 2-9μmTreatmentGlazed, polishingDimensionCustomizedJoining typesCeramic + Mo/Mn Metallized + plating NiCeramic + Mo/Mn Metallized + plating AgCeramic + Mo/Mn Metallized + plating AuCeramic + printing Ag Application> Feedthrough> Metal/alloy ceramic metallized> Screen Printing> Roll Printing> Hand Painting> Air Brush Spraying> Immersion> Centrifugal Coating> Needle Painting Alumina Ceramic PropertiesPropertiesUnitsAlumina CeramicPuritywt%95%99%99.8%Volume Densityg/cm33.653.8≥3.89Water Absorption%000Crystal Size(Grain Size)μm4-54-54-5Vickers Hardness, HV1.0Gpa141600≥15Flexural StrengthMpa300310≥300Coefficient of LinearExpansion20-500oC1x10-6 mm/oC6.5-7.56.5-7.56.5~7.520-800oC6.5-8.06.5-8.06.5~8.0Thermal ConductivityW/m·K( 20oC)2025≥20.9Specific Heat CapacityKJ/(kg·K)≥0.8≥0.8≥0.8Dielectric StrengthKV/mm≥1215*106≥12Volume ResistivityΩ·cm 20oC≥1014≥1014≥1014Ω·cm 300oC≥1011≥1011≥1011Ω·cm 500oC≥109≥109≥109Dielectric Constant1MHz99-109-10Tangent of Dielectric Loss1MHz≤4x10-4≤2x10-4≤3x10-4Surface Roughnessμm0.4 After Machine0.1-0.4 After Machine0.1-0.4 After MachineMax Working TemperatureoC160016001650
