METHOD FOR PREPARING ALUMINUM SUBSTITUTED GARNET |
| 摘要 |
A method for preparing a cubic phase Li7La3Zr2O12 (LLZ) includes dry-mixing Li2CO3, La2O3, ZrO2 and Al2O3. The mixture is fired at 800° C. to 1,000° C. for 5 to 7 hours, naturally cooled, and dry-mixed. A pellet having a size from 8 mm to 12 mm at 120 MPa to 150 MPa is manufactured using the mixture. Then, the pellet is fired at 1,000° C. to 1,250° C. for 20 to 36 hours. |

1. A method for preparing a cubic phase Li7La3Zr2O12 (LLZ), the method comprising:
dry-mixing Li2CO3, La2O3, ZrO2 and Al2O3 to form a mixture; firing the mixture at 800° C. to 1,000° C. for 5 to 7 hours; naturally cooling the mixture and then secondly dry-mixing the mixture; manufacturing a pellet comprising the mixture having a size from 8 mm to 12 mm at 120 MPa to 150 MPa; and firing the pellet at 1,000° C. to 1,250° C. for 20 to 36 hours. |
