Reference
The relative density of Barium bis(dihydrogenorthophosphate) (CAS 13466-20-1, EC 236-715-1) was determined using the gas comparison method at a temperature of 21 °C. The determination of the relative density was performed by three- fold measurements of two independent test item samples. The individual readings are summarised in Table 1. The density of Barium bis(dihydrogenorthophosphate) (CAS 13466- 20-1, EC 236-715-1) was determined to be 2.983 g/cm³ (= 2983 kg/m³) at 21 °C.
