Medical Ceramics Questions
How are ceramics used in medical devices?
There are many types of medical devices where ceramics are used. Each device depends upon certain characteristics of the ceramic. These include:
- Hermetic, bio-compatible, electrically insulating metal-to-ceramic feedthroughs or seals within implanted pacemakers and defibrillators, cochlear implants, and spinal cord and deep brain stimulators
- High-voltage resistant ceramic insulators within x-ray generators of x-ray and computed tomography (CT) imaging equipment need a dielectric strength great enough to withstand intense electric fields
- Thermally and electrically insulating, hard, wear-resistant, bio-compatible ceramics parts used within hand-held and robotic electro-powered surgical tools
- Biocompatible, wear-resistant components in blood collection, processing, and analysis equipment
- Reflective and uniformly thermally insulative ceramic components in lasers used for surgical and aesthetic treatments
- Heaters, nebulisers and quadrupole holders/spacers for mass spectrometers used within the pharmaceutical industry
Why are ceramics used in biomedical applications?
In addition to certain ceramics being considered biocompatible, other properties such as hermeticity, electrical and thermal insulation, hardness, wear or erosion resistance can provide the performance the specific device requires.
Why are Morgan’s ceramics particularly suitable for high voltage medical applications?
Electrical resistivity increases with ceramic material purity, which means a conventional alumina of 94% purity will deliver a decreased dielectric strength (of 8.6 kV) compared with market-leading alternatives like Morgan’s Alumina AL-300®, with purities of 97%, achieving dielectric strength of 15 kV/mm in alternating current (AC).
What are the benefits of ceramics in medical power tubes?
For high-voltage applications, the key benefits to specifying power tubes which have been manufactured using high-purity alumina to achieve a dielectric strength of 15 kV/mm in AC can be summarised in three points, smaller components, optimised performance, and increased lifespan.
