Avogadrite
Avogadrite ((K,Cs)BF4) is a potassium-caesium tetrafluoroborate. Avogadrite crystallizes in the orthorhombic system (space group ''Pnma'') with cell parameters ''a'' 8.66 Å, ''b'' 5.48 Å and ''c'' Å 7.03. The mineral is only found as a sublimation product around volcanic fumaroles.〔 ==History==
The mineral was discovered by the Italian mineralogist Ferruccio Zambonini in 1926. He analyzed several samples from the volcanic fumaroles close to Mount Vesuvius and from the Lipari islands. He named it after the Italian scientist Amedeo Avogadro (1776–1856).
