About LomonosoviteHide

Russian scholar and poet, Mikhail Vasil’evich Lomonosov.

Formula:

Na₅Ti₂(Si₂O₇)(PO₄)O₂

Colour:

Dark cinnamon-brown to black, also rose-violet

Lustre:

Adamantine, Vitreous, Greasy

Hardness:

3 - 4

Specific Gravity:

2.88 - 3.13

Crystal System:

Triclinic

Member of:

Murmanite Group > Seidozerite Supergroup

Name:

Named in honor of Mikhail Vassil’evich Lomonosov (Михаил Васильевич Ломоносов) (19 November 1711, Mishaninskaya, Archangelgorod Governorate, Tsardom of Russia - 15 April 1765, Saint Petersburg, Russian Empire), polymath who made contributions in the areas of natural science, chemistry, physics, mineralogy, history, art, philology, and language. He wrote multiple books on geology/mineralogy and discovered the law of constancy of interfacial angles, relating it with inner structure of crystals.
