N2 - A pressurized electrostatic levitation furnace (PESLF) was used to measure the density of calcium aluminate with a composition of CaAl2O4 (CA) over a wide temperature range of 673-2300K with an ultraviolet-based imaging technique. The density was measured in various gas atmospheres of O2, air and N2 at a chamber pressure of 4×105Pa. The measurements under these different atmospheres suggested that the density increased when decreasing the oxygen atmosphere. The density obtained under N2, air and O2 gas atmosphere can be expressed asρ(T) N2=2.91×103-0.073(T-Tm), ρ(T) air=2.76×103-0.075(T-Tm) and ρ(T) O2=2.70×10 3-0.1(T-Tm) (kgm-3) (±2%) with Tm=1878K, over the range 2200 to 673K.
