Abstract

original image

Ozon auf Eis gelegt: Aus einer O3+O2+CO2-Gasmischung kann ein Clathrat-Hydrat gebildet werden (links im Bild; das O2+CO2-Hydrat ist zum Vergleich gezeigt), dessen blassblaue Farbe wahrscheinlich von den darin eingeschlossenen Ozonmolekülen herrührt. An Luft bei Normaldruck und −25 °C bleibt das Ozon (0.1 % Massenanteil) im O3+O2+CO2-Hydrat mehr als vier Wochen lang erhalten.
