2,Formula wt: anhydrous 163.94 ; Formula wt: dodecahydrate 380.12
3,CAS: anhydrous [7601-54-9]; CAS: dodecahydrate [10101-89-0]
4,Specificity: A kind of six side crystallize in the shape of
needle. Can melt in water, can not melt in organism aqua. Relative
density is 1.62 (20°C). The temperature reach the 73.3-76.7°C it
will melt. It vaporizes. When the temperature reach 100°C it will
lose water change into Na3PO4. Aqueous is alkaline, erode to the
skin.
