Preparation of BaTiO3 particles using oxalate process.
| | Step 1: synthesis of mixed oxalate | | TiCl4 + H2O TiOCl2 + 2HCl (1)
BaCl2 + TiOCl2 + 2H2C2O4 + 4H2O BaTiO(C2O4)2·4H2O + 4HCl (2) | |
| | Step 2: thermal decomposition | | BaTiO(C2O4)2·4H2O BaTiO(C2O4)2 + 4H2O (3)
BaTiO(C2O4)2 0.5BaTi2O5 + 0.5BaCO3 + 2CO + 1.5CO2 (4)
0.5BaTi2O5 + 0.5BaCO3 BaTiO3↓ + 0.5CO2 (5) | |
