correct storage of nabh4
- Thread starter Mr.blank00
- Start date
Glass bottles with metal screw lids (better new, not used) that have soft polymer coating inside.
Good for many years of storage if not used too frequently.
But after first transfer you need once every first few weeks release very gently built up pressure, but not fully open cap.
Later you can check hydrogen pressure once a year or so.
It is good to have slight positive pressure inside to prevent suck backs of humid air via temperature cycles.
There is no chance of explosion of bottles up to 1L after first releases because hydrogen anyway very slowly leak through polymers.

I don't know your source, but my powder was very fluffy free flowing white powder with very low density, less than 0.2 kg/L,
so I transferred my 1kg to 5x1L bottles.
Obviously should not be stored in a thin plastic for a long, but once you open it, better to transfer whole kilogram within one hour.

no, just do not pour acid on it or smoke nearby.
temporarily you can store it in HDPE plastic bottles.
if powder is fully open and in free contact with air then it will slowly react with humidity to release hydrogen and become hard rock.
