Ulexite and Thulite Physical Properties

Ulexite and Thulite Chemical Formula

While comparing Ulexite and Thulite 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 Ulexite and Thulite chemical formula.

• Chemical formula of Ulexite- NaCaB 5O 6(OH) 6 · 5H 2OMichael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Thulite- Ca₂Al₃(SiO₄)₃(OH)

Ulexite and Thulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Ulexite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ulexite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Ulexite is 3.1 whereas that of Thulite is 3.1.
