METHOD FOR PREPARING MULLITE FROM KAOLIN |
| 摘要 |
FIELD: chemical technology, materials technology. ^ SUBSTANCE: method for preparing mullite involves mixing kaolin with ammonium bifluoride in the mass ratio kaolin to ammonium bifluoride = (1:1)-1.1, roasting to temperature 350-6000C and caking at temperature 1200-13000C. Invention provides preparing pure mullite without silicon oxide as impurity. ^ EFFECT: improved preparing method. ^ 1 ex |
