<p>For ternary Al-NiO-Ni system:</p> <p>1. Figures 4-1 and 4-2 show the particle characteristic of the reagents.</p> <p>2. Figures 4-3 and 4-4 show the EKVI simulated results for two binary systems (Al-NiO and Al-Ni).</p> <p>3. Figure 4-5 shows the EKVI simulated results for the ternary Al-NiO-Ni system.</p> <p>4. Figures 4-6 and 4-7 show the combustion performance of the binary system Al-NiO and ternary Al-NiO-Ni system.</p> <p>5. Figure 4-8 confirmed the phases of the components of the residues obtained from the combustion in different delay elements.</p> <p><br></p> <p>For ternary Sn-Bi2O3-Mn system:</p> <p>1. Figures 4-9 and 410 show the particle characteristic of the reagents.</p> <p>2. Figures 4-11 and 4-12 show the EKVI simulated results for two binary systems (two thermites and two intermetallic systems),</p> <p>3. Figure 4-13 shows the EKVI simulated results for the ternary Sn-Bi2O3-Mn system.</p> <p>4. Figure 4-14 shows the combustion performance of binary systems and ternary Sn-Bi2O2-Mn system.</p> <p><br></p> <p>For pictures of the table's data:</p> <p>1. Tables 3-1, 3-2 and 3-3 list the details of the reagents, compositions and the preparation of delay elements.</p> <p>2. Tables 4-1 and 4-11 list the main dominant reactions that occurred during the combustion process.</p> <p>3. Tables 4-2 and 4-7 list the different combustion rates of the compositions compacted in different types of delay elements.  </p> <p>4. Table 4-3 lists the XRF results of Sn, Mn and Bi2O3 particles.</p> <p>5. Table 4-4 lists the details of binary and ternary systems designed for the Sn-Bi2O3-Mn system.</p> <p>6. Tables 4-5 and 4-6 list the burning rates of compositions for the Sn-Bi2O3-Mn system employed in glass tubes and open air.</p> <p>7. Table 4-8 lists the mixture model coefficients used for the Sn-Bi2O3-Mn system.</p> <p>8. Tables 4-9 and 4-10 list the phases of the components of the residues obtained from the combustion in different delay elements.</p>
