The photo left shows a sample of KC1O3 powder inside a diamond anvil cell with reddish damage spots (near the center) of molecular oxygen after x-ray bombardment at 15 GPa. The clear bubbles are ruby spheres.
A novel method to load oxygen in a sealed diamond anvil cell, via the x-ray induced decomposition of potassium chlorate (KClO3) is demonstrated. It is anticipated that this technique will be useful in loading even more challenging, difficult-to-load gases such as hydrogen and also to load multiple gases.
