The Tc of this ceramic superconductor was confirmed by Dr. Ron Goldfarb at the National Institute of Standards and Technology-Colorado in February of 1994. Under extreme pressure its Tc can be coaxed up even higher - approximately 25 to ... [For additional, more-obscure history, visit the "Atypical" and "Type 2"pages.]

THE HISTORY OF SUPERCONDUCTORS Superconductivity was discovered by H. Kamerlingh-Onnes in Holland in 1911 as a result of his investigations leading to the liquefaction of helium gas. In Onnes' time superconductors were ... In February of 1987, a perovskite ceramic material was found that was a superconductor at 90 Kelvin.

THE HISTORY OF SUPERCONDUCTORS ... In February of 1987, a perovskite ceramic material was found that was a superconductor at 90 Kelvin. This was very significant because now it became possible to use liquid nitrogen as the refrigerant.

This theory predicted that the maximum temperature that a superconductor could function at was about 30K (-247°C). This meant that there was somewhat of a shock in 1986 when there a superconductor discovered which became superconducting at 35K and others rapidly developed at 92K (Yittrium Barium Copper Oxide) with...
