  1. 090121 Synthesize of Li-intercalatedZrNCl and ZrNBr Superconductor(Dikti Sandwich Program in IMR Tohoku Unv.) Andhy Setiawan Bandung Institute of Technology (ITB)

  2. Synthesize of Li-intercalatedZrNCl and ZrNBr Superconductor(Dikti Sandwich Program in IMR Tohoku Univ.) Have been presented on January, 21st 2009 by AndhySetiawan In IWASA Lab. IMR Tohoku University Sendai, January, 29th 2009 Prof. Yoshihiro IWASA

  3. Getting new experiences Introduction • Dikti Sandwich Program is purposed to facilitate graduate students of Indonesia University to have a certain experience in overseas university • ITB<=>IMR PECVD Lab. (ITB) IWASA Lab. (IMR) • Synthesize of Li-intercalated ZrNCl and ZrNBr Superconductor

  4. Synthesize Procedure and Its Apparatus

  5. Some Properties Measurement and Its Apparatus

  6. Experiment • Synthesize of ZrNCl : • ZrH2 (1g) + NH4Cl (10 g) • Synthesize of ZrNCl (NMR) : • ZrH2 + NH4Cl (15N) • Synthesize of ZrNBr : • ZrH2 + NH4Br • Purification of ZrNCl and ZrNBr • Intercalation (synthesize of LixZrNCl, LixZrNBr) • Measurement

  7. 400 0C 600 0C N2 NH4Cl 10 g ZrH2 1 g Synthesize of ZrNCl Step 1 : Synthesize of ZrNCl

  8. 750 0C 850 0C ZrNCl + 0.1NH4Cl Pure ZrNCl Purification of ZrNCl Step 2 : Purification

  9. 750 0C 850 0C ZrH2 + 15NH4Cl (ZrH2 + NH4Br) 750 0C 850 0C ZrNCl + 0.1 15NH4Cl (ZrNBr + 0.1 NH4Br) Pure ZrNCl (ZrNBr) Synthesize and Purification of ZrNCl (NMR) and ZrNBr Step 1 : Synthesize Step 2 : Purification ZrNBr

  10. Intercalation • Intercalation Li to ZrNCl

  11. Intercalation • Intercalation Li to ZrNCl (NMR) • Intercalation Li to ZrNBr (will be done) • x = 0.05 – 0.15

  12. c b 600 a Cl Zr N Measurement Crystal Structure of ZrNCl (x-ray powder diffraction) (003) (110) 9.47 49.2 a = b = 3.602 Ǻ , c = 27.246 Ǻ

  13. Measurement Magnetization of LixZrNCl

  14. Measurement Resistivity of LixZrNCl

  15. Conclusion I have learned to • Synthesize of Li-intercalated ZrNCl and ZrNBr superconductor. • Measure the crystal structure, magnetization, and resistivity.
