Thermal Decomposition of Calcium Nitrate?

Calcium Nitrate Ca(NO3)2 is kind of oxydizer that release Oxygen when it's heated.

Does anybody know, at what temperature Ca(NO3)2 will decompose and release oxygen?

Thanks in advance

    it looks like around 676 Celsius, (949K)

    http://www.sciencedirect.com/science?_ob=ArticleUR...

    "Anhydrous calcium nitrate melts at 836 ± 2 K and subsequent decomposition occurs in the liquid phase. The temperature of NO−3 anion breakdown under dynamic rising temperature conditions increases with the heating rate, being 949 K at 10 K min−1. "

    "... measurements of gaseous product evolution... is approximately summarised as Ca(NO3)2 → CaO + 1(1/2)NO2 + O2 + (1/4)N2)"
