Material Circulation, Mineral Resource

Current status of mineral, metals, and materials, and scope for the future are introduced.

Demands for mineral resources, especially these for rare metals or minor metals, are increasing in the recent years. For example, a large quantity of rare metals is necessary for producing hybrid vehicles and electronic vehicles because these advanced vehicles require high efficiency, large motors, and large batteries.It would not be an exaggeration to say that next-generation vehicles will be moving rare metals.

Furthermore, solar-energy conversion by photovoltaic cell also requires large amount of rare metals. LED, light-emitting diode, for energy saving lighting also requires rare metals. In this lecture, some misconceptions and prejudices related to rare metals, which are indispensable for the high-tech industry, are introduced.

Information on some hazards associated with using metals is also explained. Importance of materials circulation of these metals is discussed in the lecture.
