Mystery:
Is this mineral TiO or TiC (latter being end-member of khambravateit)?
There is conflicting info on the web.
Seems evidence mounts for TiO.
Simple cubic rock salt structure, so much is sure.
TiO
- mindat.org Hongquiite – Mohs 3.5 (odd, seems a bit soft)
- webmineral.com Hongquiite – Mohs 5.0 to 6.0

TiC
- German mineral atlas Hongquiite Mohs 5.5 to 6.0
- euromin Hongquiite Mohs 5.5 to 6.0 (odd, TiC should be harder)
