Refractive Index:Index of refraction: 2.20 (liquid) at 20 °C
Water Solubility:Partially sol in biological fluids (gastric juice, plasma, etc)
Experimental Properties:Heavy, infusible|Hardness 6.5 (Mohs)|Amorphous thoria crystallizes upon fusion with sodium carbonate or potassium orthophosphate.|Thoria forms double oxides with the alkaline earths, eg, thorium barium oxide (12230-90-9). Double oxides with the alkali metals are of the type sodium thorium oxide (12058-67-2). It also forms oxides with germanium, titanium, vanadium, niobium, tantalum, and molybdenum.|For more Other Experimental Properties (Complete) data for THORIUM DIOXIDE (6 total), please visit the HSDB record page.
