Superconducting materials – A sign of new material

There has been a long history in the development and discovery of superconducting metals. This discovery, in 1911, has attracted attention from researchers around the world. Despite making significant advances in its research, the application of this material is still in development. It was only until 1986 that superconducting elements were discovered at high temperatures.

The development of high-temperature superconducting substances and related technology took more than twenty years. Today, they are used for power, transportation, as well as medical purposes. Because superconducting is an emerging technology in science and technology today, it has high strategic and commercial significance and has many potential applications. A new industrial revolution will undoubtedly result from the widespread adoption of superconducting technologies and their wide use.
Application status of high temperature superconducting substances
HTS material applications can generally be divided into strong and weak current categories. All superconducting uses are built on the characteristics of zero resistance, complete diamagnetism, and superconductors’ high critical current density. Most superconducting applications are dependent on the energy gap, tunnel and magnetic flux. Strong electric fields like power systems are the main use of HTS strip and blocks. While superconducting, thin-film HTS is used to make superconducting, quantum interference devices. This has a wide range of applications in weak electric forces.
Use status for high temperature superconducting substances in the area of strong electricity
HTS superconducting minerals were found to have special applicability properties. Application research for high power began in the early 1990s. Early research was focused on making high temperature superconducting leads, including coil magnet technology. Presently, the use of superconducting materials at high temperatures has led to significant advances in energy and transportation as well high energy physics.

(1) Used for power energy it can be used as HTS Cable, HTS Transformer, Superconducting Magnetic Energy Storage, Superconducting Flywheel Energy Storage, HTS Motor, HTS Generator, or HTS Current Lead in Test and Development Stage.

HTS maglev train and superconducting magnetic propulsion ship have been successfully developed in transportation. HTS technology may also be employed in electric cars, planes and other horizontal or vertical transportation systems.

(3) Biological medicine is widely used for superconducting Magnetic Resonance Imaging Device.
Furthermore, high energy physics research is often used as a detector magnet/transport magnet and an accelerating magni. Military field is also dominated by superconducting technologies such as the superconducting electromagnetic gun, superconducting radar weapon, and superconducting superconducting sweeper. These advantages include very low cost and elimination of dead zone. It also has weak target signal characteristics. High system security is assured. It is extremely strategic for national defense because superconducting arms and equipment play a critical role. The current international circumstances make it reasonable to suppose that superconducting research in the military area will see more attention.

Application Status of High-temperature Superconducting Materials within the Fields of Weak Electricity
There are many uses for high temperature superconducting metals in the fields of weak current (and weak magnetic force), especially in electronics, communication, and in communications.

(1)In superconducting electronics the SQUID inductors (superconducting computer) are used for earthquake prediction, space and military purposes.

(2)HTS filters, which are for mobile communications and other field, can be found in the communication sector. Also, there is HTS microstrip antennas, used for communications, navigation and various other fields. Superconducting filters offer many benefits, including a steep signal-to-noise, high selectivity, excellent anti-interference and strong selection. 3G coverage will extend to all of Japan’s prefectures as well, the majority of counties, municipalities, major highways and picturesque spots. In the future, there will be more than 400 000 3C base stations. To build a network you will also need 4C network design, network optimization, and upgrading. The market for 10 million will grow if superconducting filters are used in 20% of new basestations.

(3)Other applications of weak currents include superconducting superconducting magnet shielding, military and laboratory research, superconducting superconducting cables, superconducting submarines and large-sized naval vessels.
Epilogue
After 20 years of work, the properties and preparation technology of superconducting high-temperature materials are finally mature and can be used in large-scale industrialization. With the development trend towards energy saving and environmental protection in the future, the potential market value for high temperature supraconducting products is enormous. High-temperature superconducting and related materials are also in strong demand. To make high temperature superconducting metals practical again, it will require the cooperation of government agencies as well scientific research centers and companies.
