摘要：
The ternary system H2O-NH4NO3-Al(NO3)(3). II. The polythermic diagram up to 100 degrees C. The solid-solid equilibrium diagram of H2O-NH4NO3-Al(NO3)(3 .)6H(2)O composition field is completely established up to 100 degrees C. A quasibinary eutectic and ten ternary isobar invatiant transformations are observed by thermal analysis and fully characterized: liq. E <----> ice + NH4NO3 V + Al(NO3)(3 .)9H(2)O at - 33.6 degrees C at - 33.6 degrees C liq. T-1 + NH4NO3 IV <----> ice + NH4NO3 V at - 18.8 degrees C at - 18.8 degrees C liq. Q(1) + Al(NO3)(3 .)8H(2)O alpha <----> Al(NO3)(3 .)9H(2)O + NH4NO3 IV at - 12.3 degrees C liq. T-2 + NH4NO3 IV <----> Al(NO3)(3 .)9H(2)O + NH4NO3 at - 18.8 degrees C liq. T-3 + NH4NO3 IV <----> NH4NO3 V (binary) at 32 degrees C liq. T-4 + NH4NO3 III <----> Al(NO3)(3 .)8H(2)O alpha + NH4NO3 IV at 32 degrees C liq. T-5 + Al(NO3)(3 .)8H(2)O beta <----> Al(NO3)(3 .)8H(2)O alpha + Al(NO3)(3 .)9H(2)O at 37.0 degrees C liq. T-6 + Al(NO3)(3 .)8H(2)O beta <----> Al(NO3)(3 .)8H(2)O alpha + NH4NO3 III at 37.0 degrees C liq. Q(2) + Al(NO3)(3 .)6H(2)O <----> Al(NO3)(3 .)8H(2)O beta +NH4NO3 III at 41.0 degrees C liq. T-7 + Al(NO3)(3 .)8H(2)O gamma <----> Al(NO3)(3 .)8H(2)O beta + Al(NO3)(3 .)9H(2)O at 51.0 degrees C liq. T-8 + Al(NO3)(3 .)8H(2)O gamma <----> Al(NO3)(3 .)6H(2)O beta + Al(NO3)(3 .)8H(2)O beta at 51.0 degrees C.
