correct storage of nabh4

[Mr.blank00]

Can you share your experiences on how to store Nabh4 correctly, and what if the humidity is too high, what will happen? Thank you

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.

If it's still in 1kg vacuum plastic, the weight is nabh4, can it be stored for a long time, or does it have to be separated into 20-25gram bottles.

 

[FENTAMAS]

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.

 

[Mr.blank00]

Sorry friend, is there a possibility of burning or exploding if exposed to outside air for too long? Sorry, I bought 2kg and 1kg is still in its original plastic. I'm afraid of what will happen because I don't have much information about this Nabh4.

 

[FENTAMAS]

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.

OK, thanks for the information friend. Thank you for your time.
