Tornés-Blanco Anibal Alicea-Pauneto Abneil Colón-Rivera Ramón González-Piñeiro Ann
INTRODUCTION
Background Info ❏ Solid-state synthesis
❏ Branch of material chemistry : Mix & match solids.
❏ Why is this study so important? ❏ Obtain new compounds with unique
properties to aid the technologically dependent world we live in.
Cornerstone of technology❏ Superconductors such as high purity silicon and catalysts like platinum, took a pivotal role in the
industrialization process during the 20th century.
Chen et al. 2015
“In recent years, electrochemical capacitors, also known as supercapacitors, have received a large amount of attention as an important power storage device due to their high power density, fast recharge capability and long cycle life .”

Problem
❏ Synthesize new compounds from the combination of different metals from the families 13, 14, 15, chalcogens (group 16) and intrinsic Oxygen.
Hypothesis❏ After heat application, oxidation reactions will occur and
hopefully, crystals will appear .
❏ This is a trial and error experimentation

Results
We found Crystals!
But not the type we expected...
Ternary Reactions I 5 In : 3 Sb 5 Sn : 3 Pb
Ternary Reactions II 5 Bi : 3 Pb 1 Bi : 2 Pb
Ternary Reactions III1 In : 1 Sb 1 In : 1 Bi
Ternary Reactions IV 2 In : 1 Sn 2 In : 1 Pb
Conclusions❏ The results were partially positive making allusions to our
hypothesis.
❏ We obtained Oxide Powder.
Limitations
❏ Time Limitation
❏ Only one high temperature vacuum tube furnace,
named ¨Lisa¨ .
❏ Oxygen insulating equipment
Future Work
❏ Try new combinations of ternary and quaternary
compounds
❏ Analyze the data collected with the appropriate
instrumentation
