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?

Also magnesium based compound that is only slightly water soluble but fluorine is not terribly abundant and a health risk in too high concentrations:
- MgF2 Magnesium fluoride mineral sellaite – Mohs 5.0 to 5.5 – 3.15g/ccm – very slightly soluble in water (0.13g/liter) – rutile structure
