persink
Persink is a rare and unique mineral that was first discovered in 1984 in the Khibiny Massif, Kola Peninsula, Russia. It is named after the Russian word "perspektivny," which means "promising," reflecting the mineral's potential for future scientific and industrial applications. Persink is a complex oxide mineral with the chemical formula Na2Ca2Ti3(Si2O7)2O2. It crystallizes in the monoclinic system and typically forms small, dark brown to black crystals or granular masses.
The mineral's structure is characterized by a framework of corner-sharing TiO6 octahedra and SiO4 tetrahedra, with
Persink has been studied for its potential applications in various fields, including electronics and optics. Its
