The word "ceramic" is derived from the Greek word κεραμικός (keramikos) meaning pottery. It is related to the older Indo-European language root "to burn". [2] "Ceramic" may be used as a noun in the singular to refer to a ceramic material or the product of ceramic manufacture, or as an adjective.
Electroceramics are a class of ceramic materials used primarily for their electrical properties.. While ceramics have traditionally been admired and used for their mechanical, thermal and chemical stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics ...
Piezoelectric materials (PMs) can be broadly classified as either crystalline, ceramic, or polymeric. [1] The most commonly produced piezoelectric ceramics are lead zirconate titanate (PZT), barium titanate, and lead titanate. Gallium nitride and zinc oxide can also be regarded as a ceramic due to their relatively wide band gaps.
The key advantage of this type of ceramic material is the versatility afforded by the use of polymeric precursors in terms of processing and shaping. Polymer derived ceramics can be additively manufactured (3D printed) by means of fused filament fabrication , [ 4 ] stereolithography that uses photopolymerization of preceramic polymers . [ 5 ]
Ceramics are now commonly used as dental and bone implants. [8] [9] Surgical cermets are used regularly. Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response. Other examples of medical uses for bioceramics are in pacemakers, kidney dialysis machines, and respirators. [6]
Ceramic mold casting, also known ambiguously as ceramic molding, [1] is a group of metal casting processes that use ceramics as the mold material. It is a combination of plaster mold casting and investment casting. [2] [3] There are two types of ceramic mold casting: the Shaw process and the Unicast process. [4]
