Medical Materials and Benefits
Our ceramic materials provide superior wear, strength, and electrical characteristics for structural applications like x-ray tubes and robotic surgical tools. Ceramic materials provide a barrier to prevent bodily fluid ingress and resistance to harsh reagents and cleaning chemicals used in medical instruments, making them an excellent choice for haematology applications.
Key Material Properties
- Biocompatibility
- Durability
- Hardness
- Wear and chemical resistance
- Electrical insulation
- Hermeticity
- Low wear-rate
- Fracture toughness
- Long-term chemical stability
- Radio Frequency (RF) transparency
Our precision brazed ceramic-to-metal assemblies are used in new treatments to ablate tumours. The minimally invasive procedure means that patient trauma following surgery is reduced and post-operation recovery times are significantly shorter.
Medical Products Capabilities
The combined features of biocompatibility, dielectric and mechanical strength, chemical resistance, and low-wear of our ceramics; our broad array of braze alloys and our capabilities to develop custom alloys; and our expertise in metallising and brazing enable experts from our world-wide facilities to collaborate with our customers designers to develop customised solutions for their most challenging needs.
The results are customer innovations that provide lower costs, improved therapies and analytics, and improved patient outcomes.
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 lternating 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.

As highly experienced specialists, we help the developers to make the required insulators "ceramic-friendly". This lowers development costs and protects the budget, shortens the development time and enables a faster "time to market”; but most importantly, production costs can be kept low from the outset.
