Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 11075-2003 “Lithium carbonate”. As compared
with GB/T 11075-2003, the main technical changes of this Standard are as
follows.
- ADD lithium carbonate produced from brine as raw material to the scope of
application;
- Product’s water content is separated from the previous chemical
composition and becomes a separate inspection item;
- Reduce the content of impurity elements such as Na, Fe, etc. and water
content in the product;
- Increase the content of chloride ion impurity element in the product;
- The lot grouping weight is changed from the previous net weight 1 t ~ 18 t
each lot to the net weight of not more than 20 t each lot of products;
- The net weight of each bag is changed from 25 kg±25 g to 20 kg ~ 1000 kg.
This Standard shall be under the jurisdiction of National Technical Committee
243 on Non-ferrous Metal of Standardization Administration of China (SAC/TC
243).
