Mg-GAP pyrolant

The results of thermochemical experiments reveal that an exothermic reaction of GAP occurs at about 526 K and that no other thermal changes occur. When Mg or Ti parhcles are incorporated into GAP to formulate Mg-GAP or Ti-GAP pyrolants, two exothermic reactions are seen the first is the aforementioned exothermic decomposihon of GAP, and then a second reachon occurs at 916 K for the Mg-GAP pyrolant and at 945 K for the Ti-GAP pyrolant There is no reaction between either Mg or Ti and GAP at the temperature of the first exothermic reaction. Both Mg and Ti particles within GAP are ignited by the heat generated by the respechve second exothermic reactions. 

X-ray analysis results show the formation of MgN as a combustion product of Mg-GAP pyrolants. The reaction occurs with nitrogen gas formed by the decomposition of GAP according to ... 

However, no MgO is seen in the residue, indicating that this compound is not produced by reaction between Mg and CO. On the other hand, no TiN is seen in the residue of the Ti-GAP pyrolant, implying that there is no reaction between Ti and Nj to produce this compound. Ti particles react exothermically with carbon formed by the decomposition of GAP according to ...
