High Brazing Strength Metallized Ceramic Tubes for Feedthru

Technical Key Parameters of metallized ceramic tubes Leak Rate ≤1 x 10-11 Pa.m3/s Metal Layer Tensile Strength ≥150 Mpa Volume Resistivity ≥108Ω•cm Coefficient of Thermal Expansion (6.5 ~ 8.0) × 10-6 /°C Insulation Strength ≥18 kV/mm (D•C) Dielectric Constant 9~10(1MHz, 20°C) Cosmetic Quality:1. No cracks, no bubbles; 2. Evenly distributed glaze; 3. No contamination The description of metalized ceramics Depositing a metallic coating of Molybdenum-manganese(Mo-Mn) / Tungsten (W) based paints followed by nickel /gold plating, Afterwards, an interface offered that enables ceramic to metal or ceramic to ceramic joining by means of brazing via solder. In common case, a layer of metallization layer is applied with a typical thickness of 10 to 30 µm after cured…
