Olgite is a blue-green colored mineral that forms microscopic prismatic crystals that are trigonal in structure. Its chemical formula is written as Na(Sr,Ba)PO4 and its composition are listed as follows:
- Barium 27.11% Ba 30.27% BaO
- Sodium 10.09% Na 13.59% Na2O
- Strontium 21.14% Sr 25.00% SrO
- Phosphorus 13.59% P 31.14% P2O5
- Oxygen 28.08% O
Olgite as of present time is the series name for bario-olgite and strontio-olgite. The substance was named after Olga Anisimovne-Vorobiova, a Russian mineralogist.
