We are interested in receiving the contact details of China's metallurgical-grade alumina manufactures/exporters. Actually, we need the exact grade of the alunina. But I think this is the regular grade for most manufactures/exporters.

Just in case, above is the chemical composition of this grade of alumina. The content of Na2O is especially important to us.

We need statistical data on the content of Na2O in alumina over a long period.
