Metallized Alumina Ceramic For Medical CT Tube Insulators
Meetcera Technical Ceramics produces reliable medical X-ray components—including anodes, cathodes, complete X-ray tubes, and getter assemblies—using advanced ceramic-to-metal sealing technology. We combine high-purity alumina ceramics with various metal components, achieving hermetic sealing through molybdenum-manganese metallization and brazing processes.
Main Product Types
- Anode and Cathode assemblies
- Complete X-ray Tubes
- High-voltage insulators, feedthroughs, and custom ceramic-to-metal components
Unique Selling Points
- Extreme Dielectric Stability: Engineered to withstand 100kV+ operating voltages, our ceramics prevent internal arcing and dielectric breakdown. This solves the primary failure mode in high-speed CT scanners, ensuring uninterrupted clinical diagnostics.
- Ultra-High Vacuum (UHV) Integrity: Featuring a helium leak rate of <1×10⁻¹⁰ mbar·l/s, our components guarantee the vacuum longevity required for expensive medical tubes. We solve the “vacuum decay” issue that often shortens the lifespan of X-ray devices.
- Medical-Grade Purity & Traceability: Using 95%-99.9% high-purity Alumina with zero organic contaminants. This ensures low outgassing and prevents cathode poisoning in the vacuum tube, meeting the stringent standards of global medical device OEMs.
- Perfect Thermal Expansion Matching: Our Mo-Mn metallization is optimized for Kovar or Stainless Steel brazing. This solves the “thermal stress cracking” problem during the rapid temperature spikes inherent in high-power imaging.
Product Description
In the world of medical imaging, the reliability of a CT tube is non-negotiable. For engineers and healthcare technology providers, the ceramic insulator is the unsung hero that must maintain structural and electrical integrity under extreme high-voltage and high-vacuum conditions. A single failure in a CT tube insulator doesn’t just mean downtime; it means a halt in patient care. Our Metallized Ceramic for CT Tubes is designed to eliminate these risks at the source.
Specifically developed for CT scanners, industrial NDT X-ray tubes, these ceramic assemblies feature precision-applied Mo-Mn metallization with heavy Nickel or Gold plating. The high mechanical strength of our 95% Alumina substrate combined with our proprietary firing process ensures that the ceramic-to-metal seal remains hermetic even after multiple high-temperature brazing cycles. This makes our components the preferred choice for the next generation of high-resolution, long-life imaging tubes.
We provide more than just ceramic components; we provide the peace of mind that comes with medical-grade precision. By choosing our metallized ceramics, you are reducing your assembly rejection rates and ensuring that your imaging equipment delivers consistent, high-quality results for years.
