Heat conducting Insulating Alumina Ceramic Disc for Eswl device
Ceramic materials have been produced for custom practices for centuries but they are
a rather modern development in medical processes and applications.
Used in surgical implants, prosthetics and various medical tools
and devices, medical ceramics change lives. Manufacturers fabricate numerous ceramic medical
appliances from the oxides alumina and zirconia. Some medical
devices, specifically, ceramics-on-ceramics in artificial joint
systems, required various modifications before they became such a
widely practiced—and FDA safe—procedure. Among the latest
products of medical ceramics are electronic implantable ceramic
sensors, a blend of medical processing and modern technology.
Medical Ceramic Applications
Some common applications include:
- X-ray tubes
- Pressure sensors
- Dental screws and bridges
- Femoral head implants for hip replacement
- Hand tools
Alumina is generally composed of an aluminum and oxygen compound and is
employed in medical ceramic applications because it is typically
well tolerated by body tissue. It is also suitable as a surgical
implant because it is a very tough and hard material, and does not
wear easily. Alumina is generally composed of minuscule tightly
packed crystals. The composition results in a ceramic product that
is fracture resistant, which is crucial to safety as well as the
maximum wear of an implant.
During the initial production of alumina medical ceramics in the
1970s, the crystals were arranged more loosely, susceptible to
breaks and fracture problems in the medical implants. The hot isostatic pressure process is used to prevent such structure flaws. Also, each
manufacturer inspects the individual products before they are
employed as medical devices.
Hot Isostatic Pressure (HIP)
The hot isostatic pressure process improves the physical structure
and capability of ceramics by extracting impurities from the
material via application of an inert gas. Once the parts are dense
enough from the gas exposure, (usually processed in a chamber) they
are suitable for medical applications, though all products are
inspected before they are supplied to medical resources.
Injection Molding Technology
Injection molding is a process that involves producing parts
(usually metals and ceramics) that are intricate in design, such as
dental brackets. This process is executed by molding machines, and
numerous devices are capable of being produced in a short
time-frame. Injection molding is considered a good alternative to
previous processing, as standard stamping and machining techniques
of the past took more time and expense.
Alumina ceramic screws/nuts and bolts are used in applications
where conventional metal or plastic components will not work.
Ceramic nuts and bolts are strong, rigid, non-magnetic and operate
at high temperature and in corrosive environments.
