We manufacture a diversity of metallized ceramic insulators with customized specification, like Metallized Ceramic Tube, Metallized Ceramic Ring, Metallized Ceramic Substrate and so on. These Metallized ceramics are commonly made of high purity Alumina Ceramic , zirconia ceramic or beryllia ceramics via dry pressing, ceramic injection molding, ISO pressing or hot pressing.
We can proceed with small part-size to large part-size, the min. diameter can be 1mm, the largest diameter is up to 800mm. In order to meet customers' different needs, we offer a selection of types of metallization, the typical ones as below:
1. Ceramic base + Molybdenum (Mo/Mn) metallization ...2. Ceramic base + Mo/Mn metallization + Nickle(Ni) plating
3. Ceramic base + Silver(Ag) plating.................................4. Ceramic base + Tungsten (W) metallization + Gold(Au) plating
We offer different grade precision Metallized Ceramic Insulator when you need these ceramic components to be very precise, these vacuum ceramic components would be further proceeded via lapping, grinding, CNC machining before metallization on site production. The finest tolerance can be +/-0.001 for length, +/-0.005 for both inner and outer diameter.
Leak Rate ≤1x10-11Pa.m3/s Metal Layer Tensile Strength ≥150Mpa Volume Resistivity 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
≥108Ω•cm
Coefficient of Thermal Expansion
(5 ~ 8.0) × 10-6 /°C
Widely used in vacuum interrupters, Electron tubes,Gas discharge tube, Vacuum capacitor,Vacuum thyristors, Surge arresters, Thyristor housings, Diode housings,Power grid tubes,Traveling wave tubes,Insulator rings and cylinder,X-ray tubes and so on.
We have a complete comprehensive of production equipment for Metallized Ceramics from shaping to electroplating.It helps us to make the dimensional consistency very well. Also, helping us to offer a competitive price.
