Abstract
In order to form the ozone ice, we used micro-bubbles of containing ozone gas. In this method, not only ozone dissolving in water but also that in micro-bubbles trapped in ice are available when the ice is melting. Therefore, in this paper, O_2 micro-bubbles were used as a preliminary experiment. The cooling plate inclined downward was set in the micro-bubbles water, and then ice including a lot of O_2 bubbles was generated on the cooling plate surface. The trapping phenomenon of the bubbles was clarified by observing the distribution of O_2 bubbles in ice.
