Growth of Superconducting Single Crystals

One of the more interesting cuprate systems to display high temperature superconductivity is the infinite layer family. These materials, of the general formula MCuO2, have infinite two-dimensional CuO2 sheets separated by M ions. Crystals of the first material of this type, Ca0.86Sr0.14CuO2, grown from stoichiometric melts at 1150°C, were insulating [283]. A number of related superconducting compounds with Tc up to 110 K have been synthesized under high pressure (see Table E2.4.2 and [284]). Millimetre-sized single crystals of CaCuO2 were grown from a BaCuO2/CuO flux in yttria or alumina crucibles at an Ar gas pressure of 1000 MPa [248]. The crystals had broad transitions at superconducting onset temperatures of 70–100 K.
High-Pressure Study of Phosphors Emission

Another important application of high pressure is the ability to create entirely new crystalline structures and energy states that do not exist under normal conditions. Some of the systems modified at high pressures remain altered after pressure is released. Alternatively, the change of the local environment occurring at high pressure can be permanent, thus getting a new material with significantly different spectroscopic properties.
“From Forest to Factory to Fabrication”
Published in R. N. Swamy, Fibre Reinforced Cement and Concrete, 1992
High-pressure techniques have been used to generate materials with increased density and improved mechanical performance. This product is used in wet areas, such as bathrooms, laundries, external balconies, decking and pool surrounds. The structural properties of this product find use in bridge construction.

High pressure has played an significant role in investigating structural and physical behaviour of materials, especially in synthesising or designing materials with peculiar properties such as superhardness and superconductivity [1–5]. For instance, some of metal carbides can become superconductors by applying external pressure although they do not exhibit superconductivity at normal pressure [1,6].
