Platinum Crucibles FAQs
What are platinum crucibles?
Crucibles are containers designed to contain substances during chemical reactions. Platinum has low reactivity and a high melting point, making it excellent for controlled testing.
How to clean a platinum crucible correctly?
There are a few ways to clean platinum crucibles, each of which will prevent material transfer between experiments. You can use potassium bicarbonate, or an acid bath of either citric acid or diluted hydrofluoric acid.
Potassium bicarbonate:
Remove residues from previous samples.
Add solid potassium bicarbonate to the crucible to cover all leftover materials.
Heat the crucible until bicarbonate melts, stirring frequently for 1 minute. A layer of red potassium salt should appear on the surface.
Remove from heat, pour out bicarbonate and rinse in hot water.
Citric Acid Bath:
Place platinum crucible in an ultrasonic bath
Add citric acid (20%) to the bath and vibrate at 50oC for 10 minutes
Dry the crucible with clean air or a drying oven.
Diluted Hydrofluoric Acid (if citric acid does not work completely)
Soak in hydrofluoric dilution for >24 hours
Boil for 3 hours
Rinse with water and use ultrasonic bath if needed
Boil in distilled water to remove all traces of hydrofluoric acid
Bake at 900oC for 1 hour.
