Periclase (MgO) is a material with good properties that offers
slow but present degradability when spilled into nature.
It degrades faster than quartz.
Advantages:
- High crystal structure symmetry - simple cubic rock salt structure
- degradability
- Magnesium is a very common element
- Magnesium and its compounds are highly nontoxic environment and health friendly
Disadvantages:
- not the highest material strenght but decent
- degradability
- maybe questionable passivatability?
Basic properties:
- Crystal structure: simple cubic – like rock salt NaCl
- Hardness: Mohs 6
- Density: 3.58g/ccm
- Melting point: 2800 C°
- Water solubility: barely soluble but still measurably soluble => not suitable for externally water exposed nanomachinery

MgF2 (different crystal structure) is also a magnesium based compound that is quite a bit more but still limitedly water soluble.
But fluorine is not terribly abundant and a health risk in too high concentrations.
