Suzukiite – polymorphic to Bavsiite

Suzukiite

  • Named in honor of Jun Suzuki, a professor of mineralogy and petrology, at the Hokkaido University, Sapporo (Japan).
  • Suzukiite belongs to the inosilicates (chain silicates) and is polymorphic to Bavsiite, which is tetragonal.
  • Formula: BaVSi2O7
  • Space group: Cmcm (No. 63)
  • Crystal system: orthorhombic
  • Crystal class: mmm
  • Lattice parameters: a = 5.3546(16), b = 15.249(5) Å, c = 7.094(2) Å, α = β = γ = 90°
