説明

Recently, the power generation using renewable energy such as solar light and wind power is noticed, but these power generation methods have a problem that they are strongly affected by weather and time. Then, the magnesium battery which solves these problems and can carry out the repeated power generation is noticed. While fossil fuels are used for refining magnesium. There are problems such as depletion of fossil fuel and air pollution. Solar heat is attracting attention as an alternative energy source to fossil fuels. In this study, it is considered that magnesium is refined by solar heat, and the research was carried out paying attention to light-burned dolomite. However, there is no heating experiment data of the light-burned dolomite, so the heating characteristics were unknown, when the light-burned dolomite was heated by a solar concentrator. From the experiments which the absorptance coefficient of light burning dolomite was calculated to be from 0.49 to 0.58. From this result, it is considered that the light-burned dolomite to be high temperature is difficult by direct heating.
