Product Description

High Voltage Alumina Metalized Ceramic Insulator for Medical X-Ray Tube

1. It's made of 95% aluminum oxide ceramics which has superb mechanical, electrical thermal properties.

2. The metallic layer will be applied to a certain surface of ceramic parts which cured by high temperature;

3. Then the metallic layer will adhere the section tightly to achieve ceramic to ceramic, ceramic to metal jointing. 

4. Jointing type of metallization

● Ceramic base + Molybdenum-Manganese ( Mo - Mn) metallization,   20 ~ 40um thick

● Ceramic base + Silver ( Ag) plating,   2~ 80um thick

● Ceramic base + Molybdenum-Manganese (Mo - Mn) + Nickle (Ni) plating, Mo/Mn: 20 ~ 40um thick, Ni: 2~6um thick

● Ceramic base + Tungsten ( W) + Gold (Au) plating, W: 20~40um thick, Au:  0.2um thick 


Main features of metallized ceramic insulators:

● High bonding/brazing strength                                   ● Min. electric resistance and vacuum tightness           

● High mechanical strength, insulation strength           ● Anti-chemical, anti-aging without corrosion              

● Super wear resistance with long service life

Key performance parameters of metallized ceramics

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)

Visual quality: 1. No cracks, no bubbles; 2. Evenly distributed glaze; 3. No contamination



The main application of metallized ceramic insulators:

Metallized ceramic insulators are widely used in electronics, high-vacuum technology, sensors, and medical fields, like vacuum interrupters, electron tubes, feedthroughs, medical linear accelerators/ power tubes, photomultipliers, X-ray tubes, and pressure sensors.
