Coupled intra‐ and inter‐tunnel short‐range order in hollandites: a case study of mannardite Ba[(Ti4+)6(V3+)2]O16

Acta Crystallographica Section B, Volume 82, Issue 4, Page 439-446, August 2026.
Single‐crystal X‐ray diffuse scattering combined with Monte Carlo simulations and 3D‐ΔPDF analysis reveals complex short‐range order in mannardite, involving coupled Ba–Ba interactions within and between tunnels and framework relaxation.Mannardite, Ba[(Ti4+)6(V3+)2]O16, a mineral of the hollandite supergroup, is characterized by a tunnel structure ...

Comparison of Nigerian Barite Production with some Top Barite Producing Countries

FUOYE Journal of Engineering and Technology, 2019
Barite is a very important industrial minerals used as weighting material in the petroleum industry. The nature of barite ores, geology of barite ores based on location were discussed. This paper presents top barite producing countries in the world, their production and consumption of barite, as well as their reserve. Despite all the barite deposits in
