China Manufacturer High Voltage Metalized Ceramics For Vacuum Electronic Devices

The description of the metalized ceramics
In the ceramic to metal joining technology, a certain metallic layer on the ceramic surface is needed, like Molybdenum or Tungsten, then it could achieve in connection of metal and ceramic by means of high-temperature brazing. Metalized alumina Ceramic Parts are commonly used in many applications, like electronics, High-Vacuum Technology, Medical Technology, Sensor Technology.
The metalized alumina ceramic parts we manufactured are famous for the excellent bonding strength, super mechanical, excellent electrical insulation, exceptional thermal features.

Standard types of the metalization
1. Alumina ceramic base + silver (Ag) plating directly
2.Alumina ceramic base + molybdenum (Mo/Mn) metallization
3.Alumina ceramic base + molybdenum (Mo/Mn) metallization + nickel (Ni) plating
4. Alumina ceramic base + tungsten (W) metalization + gold (Au) plating

The key parameters capability

Leak rate	≤1×10^-11 Pa•m3 / s	Metal layer tensile strength	≥ 150Mpa
Volume Resistivity	≥108Ω•cm	CTE	(6.5 ~ 8.0) × 10^-6 /°C
Insulation strength	≥18kV/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 prime features of alumina metalized ceramics
1. High bonding/brazing strength with ideal vacuum tightness between the assembly
2. With diamond-like hardness to be 85 HRV and superb compressive strength
3. Great insulation strength and volume resistivity that fit for various high voltage high current applications
4. Chemical stability, anti-aging even if it works in a variety of harsh environments, free of rust forever.
5. Over 276 times wear resistance in comparison with stainless steel, it leads to a long service lifespan.

The typical application of metalized ceramics
Remark:
Metalized ceramics are widely used in electronics, high-vacuum technology, sensors, and medical fields,
like vacuum interrupters, electron tubes, feed-throughs, medical linear accelerators/ power tubes, photomultipliers,
X-ray tubes, and pressure sensors
