The steril carbonate crystals of appropriate bulk-density were prepared by the methods of solvent-out crystallization in optimized condition,and the uniformity of the mixing cephalosporin and steril carbonate was improved.

These intermediates include the products for penicillin, cephalosporin and lactamase inhibitors.
