During the early days, ceramics was only considered as the art of making pottery. But in today’s time, it is a general term used in science for preparing articles from flexible, earthy materials which become rigid when exposed to heat. Ceramic materials are basically nonmetallic, inorganic compounds of not just oxygen, but compounds of carbon, nitrogen, boron and silicon. They have a variety of inherent properties which make them perfect to be used in a number of industries. They are very hard and resistant to plastic deformation and high temperatures. They also have good corrosion resistance with low thermal conductivity and low electrical conductivity. Ceramic materials have many advantages in comparison to other materials. Firstly, they are much harder and stiffer than steel. Secondly, they are more heat and corrosion resistant than metals or polymers. They are less dense than most metals and their alloys, are easily accessible and are quite inexpensive.
A variety of medical ceramic services can now be availed and that too at very affordable prices. Orthopedic joint replacements, prosthesis, dental restoration and bone implants are some of the medical applications of ceramics. Braces mostly consist of metal brackets and wires. Many people fear of having a metal mouth and often refuse to wear braces altogether. Dentistry has advanced with ceramic teeth that look very similar to patients natural ones and has come up with other applications that can significantly improve a patients smile. A special type of oxide called zirconia has excellent combination of strength and toughness along with bio-inert properties and low wear rates. This oxide is now displacing alumina in applications such as femoral heads for total hip replacements. Other benefits of a zirconia implant are knee joints, shoulders, phalangeal joints and spinal implants. The material is also being used for making pace maker covers and endoscopic components.
are widely used these days. The services include metalizing, dicing and machining the piezo electric materials which helps in minimizing chipping and maintains proper adhesion of metal on the surfaces. Internal diameter slicing service can be availed at very affordable prices. It is a cost effective solution for preparing large quantities of very thin components. Isolation cutting is also done which creates an electrical separation between circuits elements present on a die. The most commonly used piezoelectric materials are lead zirconate titanates (PZT) and barium titanates (BaTiO3). They produce a voltage when a mechanical pressure is applied on them.
