Hollandite and Quartz Chemical Formula
While comparing Hollandite and Quartz physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Hollandite and Quartz chemical formula.
- Chemical formula of Hollandite- Ba(Mn++++,Mn++)8O16
- Chemical formula of Quartz- SiO2
Hollandite and Quartz Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hollandite and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hollandite and Quartz Optical Properties during the identification of gemstone. Specific gravity of Hollandite is 2.65 whereas that of Quartz is 2.65.
