Product Description

High Precision Zirconia Ceramic Parts with Metallization

The description of the metallized 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 with metal and ceramic by means of high-temperature brazing. Metallized alumina ceramic parts are commonly used in many applications, like electronics, high-vacuum technology, medical technology and sensor technology.

The metallized alumina ceramic parts we manufactured have excellent bonding strength, super mechanical, excellent electrical insulation and exceptional thermal features. 

Standard types of the metallization
1. Zirconia ceramic base +  silver (Ag) plating directly
2. Zirconia ceramic base +  molybdenum (Mo/Mn) metallization
3. Zirconia ceramic base +  molybdenum (Mo/Mn) metallization + nickel (Ni) plating
4. Zirconia ceramic base + tungsten (W) metallization + 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 typical application of metallized ceramics
Metallized 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.
