About Bukovskýite
Antonín Bukovský
Formula:
Fe3+2(AsO4)(SO4)(OH) · 9H2O
Colour:
Pale yellowish-green to grayish-green
Hardness:
5
Specific Gravity:
2.334
Crystal System:
Triclinic
Name:
Named in 1967 by František Novák, Pavel Pavondra, and Jiří Vtělenský in honor of Antonín Bukovský (1865–1950), Professor at the secondary school of Kutná Hora, Czech Republic, who first analyzed the mineral.
Chemically related to zýkaite.
Often associated with kaňkite.
Compare also Sanjuanite-Destinezite Group.
Bukovskýite is metastable with respect to scorodite, and represents an intermediate step in the conversion of the unstable gels to the stable assemblage of scorodite and iron sulfates (Majzlan et al., 2012).
