Colour:
Silver gray (synthetic)
Lustre:
Metallic
Hardness:
6½
Specific Gravity:
4.762 (Calculated)

Name:
Named for Bai Wenji (15 October 1935, Jilian China - 11 January 2019), Research Professor of Institute of Geology, Chinese Academy of Geological Sciences. He was the first person to find diamonds, native Fe and other special minerals in chromitite in the Luobusa ophiolite. He discovered and named 7 new mineral species including luobusaite, linzhiite, naquite, zangboite, yarlongite, qusongite, and native titanium.
Type Locality:
Isostructural with:
The Ti(P)-analogue of mavlyanovite and xifengite. Chemically similar, to some extent, to zhiqinite and, kangjinlaite, zangboite, UM1989-10-E:FeSiTi, and 'Unnamed (Fe-Si-Ti Alloy)'.
Physical properties were determined on synthetic materials.
