It’s making a list – Santite
What does it look like?
*sings* 'and checking it twice, gonna find out who's naughty or nice….'
SANTITE is on Crystallography 365!
What is it?
It’s a little bit of a stretch, we know (go on, you go and look for more Christmas-inspired minerals!) but here is Santite! This mineral was first identified from synthetic means, its crystal structure found in 1937. Then in 1970 a group of Italian scientists identified this material in the hills of Tuscany (hard field work, eh?). They named it after a former director of the Museum of Natural History of Italy, George Santi.
It's a very rare borate mineral, where the boron hooks up to oxygen and (rather pleasingly) forms paper chain like features running thought the structure – interwoven with potassium ions.
Where did the structure come from?
Santite, or its synthetic name potassium acid dihydronium pentaborate, is #9011411 in the Crystallography Open Database, and was found by Zachariasen in 1937.
