Ceramic is the name for some materials that are formed by the use of word ceramic comes from the Greek word κεραμικός (keramikos).Chemically, it is an inorganic compound of metal, non-metal or metalloid atoms held together by chemical bonds.. Up to the s or so, the most important were the traditional clays, made into pottery, bricks, tiles and the like, also cements and.   Superconducting Properties of Ag and Sb Substitution on Low-Density YBa2Cu3Oδ • Different concentrations of Silver (Ag) and Lead (Sb) were introduced as impurities into a YBCO ceramic compound • It was found that the addition of Ag at an optimum concentration enhanced both the critical temperature and current density of YBCO. Type II superconductors are found to have much higher critical magnetic fields and therefore can carry much higher current densities while remaining in the superconducting state. A collection of various ceramics containing barium-copper-oxide have much higher critical temperatures for the transition into a superconducting state.   Superconductivity is a remarkable phenomenon: superconductors can transport electric current without any resistance and thus without any losses whatsoever. It .

Superconducting electric machines are electromechanical systems that rely on the use of one or more superconducting elements. Since superconductors have no DC resistance, they typically have greater most important parameter that is of utmost interest in superconducting machine is the generation of a very high magnetic field that is not possible in a conventional machine. Impregnation of PMMA polymer at room temperature increased the flexural strength and modulus of the superconducting ceramic without affecting its electrical propeties. The flexural properties depended on the porosity of the ceramics, and, hence, linear and nonlinear property‐porosity relationships have been used to characterize the behavior Cited by:   The word "ceramic" comes from the Greek word "keramikos", which means "of pottery". While the earliest ceramics were pottery, the term encompasses a large group of materials, including some pure elements. A ceramic is an inorganic, nonmetallic solid, generally based on an oxide, nitride, boride, or carbide, that is fired at a high temperature. You seem pretty angry there, John. How would my family feel about it? Well my parents are both ex St Johns ambulance. I&#;d say they would agree with me in this point.I don&#;t see how or where I&#;m making money from this article or from the &#e2n0;misfortu28&#; of others??I&#;m merely challenging people to step into their own power so that they can have the life they.

GdBaCuO are high temperature ceramic superconductors, a class that includes yttrium–barium–copper oxide or YBCO ceramics, which superconduct at around K. Magnesium diboride (MgB. The HTSC superconducting materials found to date are relatively delicate ceramics, making it difficult to use established techniques to draw extended lengths of superconducting wire. Much research has focussed on layer deposit techniques, applying a thin film of material onto a stable substrate, but this is currently only suitable for small Specific energy: 1–10 Wh/kg, (4–40 kJ/kg).   In January , Karl Muller and Johannes Bednorz made a discovery that revolutionized how scientists thought of superconductors. Prior to this point, the understanding was that superconductivity manifested only when cooled to near absolute zero, but using an oxide of barium, lanthanum, and copper, they found that it became a superconductor at approximately 40 degrees Kelvin. In , W. Meissner and R. Oschenfeld discovered that a metal cooled into the superconducting state in a weak magnetic field expels the magnetic field from its interior. In , the Russian physicist V. Arkadiev first performed the now-classic experiment of using this expulsion of a magnetic field to levitate a small bar magnet above the.

Before to start the discussion and analysis of those characteristics, a small background is introduced, and this is related with the phenomenological bases of the superconducting state.

High-temperature superconductors (abbreviated high-T c or HTS) are operatively defined as materials that behave as superconductors at temperatures above nearly − °C (− °F).

This is in fact the lowest temperature reachable by liquid nitrogen, one of the simplest coolants in cryogenics. All superconducting materials known at ordinary pressures currently work far below ambient.

Superconducting technology is potentially important as one of the future smart grid technologies. It is a combination of superconductor materials, electrical engineering, cryogenic insulation, cryogenics and cryostats.
