Superconducting heater.
Background technique:
Superconductivity has always been a subject of intense interest since its discovery in 1911. Electric current without resistance means huge economic benefits that are unimaginable in energy saving, high efficiency, and environmental protection. At the same time, it is not a simple and complete Conductors, as well as the superconductor repelling magnetic field Meissner effect discovered in 1933. This is a phenomenon that a complete conductor cannot explain. It presents a new thermodynamic state of matter to humans. However, the superconducting materials researched and developed by the use of superconducting phenomena are used in industrial production, especially in the field of household appliances. Because of the many technical and technological issues involved, their application and promotion speed is relatively slow. Therefore, how to make superconducting materials Combining organically with products to benefit the public is a problem the industry needs to face and solve.
