Product Description Al2O3 Metalized Ceramic Insulator for High Voltage Vacuum Feedthroughs Product DescriptionWe manufacture a diversity of metalized ceramic insulators with different specifications, like metalized ceramic tubes, metalized ceramic rings, metalized ceramic substrates, and so on. These Metallized Ceramics are made of aluminum oxide, zirconium oxide, or beryllia ceramics via dry pressing, injection molding, 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) plating3. Ceramic base + Silver(Ag) plating4. Ceramic base + Tungsten (W) metallization + Gold(Au) platingWe offer different grade precision metalized ceramic insulators when you need these ceramic components to be very precise, these vacuum ceramic components would be further proceeded via lapping, grinding, and CNC machining before metallization on-site production. The finest tolerance can be +/-0.001 for length, and +/-0.005 for both inner and outer diameter.The prime features of alumina metalized ceramics1. High bonding/brazing strength with ideal vacuum tightness between the assembly2. 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 key parameters capability of metalized ceramics Leak rate≤1×10-11 Pa?m3 / sMetal layer tensile strength≥ 150MpaVolume Resistivity≥108Ω?cmCTE(6.5 ~ 8.0) × 10-6 /°CInsulation strength≥18kV/mm (D?C)Dielectric constant9~10(1MHz, 20°C)Cosmetic quality: 1. No cracks, no bubbles; 2. Evenly distributed glaze; 3. No contaminationThe typical application of metalized ceramicsMetalized 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 sensorsRemark:1. Metalized ceramic will be packed in a vacuum state package with desiccant.2. Then the vacuum package will be put into export use cartons individually3. If needed, it will be packed by wooden case, or loaded by export use pallet.Why choose us★ 15+ Years of manufacturing experience in OEM, ODM for producing a variety of technical ceramic parts★ In-house comprehensive manufacturing types of equipment from raw material to secondary process★ Powerful R&D and mass production capability to support and meet customized needs in a short time★ Rigorous quality control system and processes from incoming material to shipping of finished goods ★ Surpassing pre-sales and after-sales service, all actions we do are just for customers' business growth
