Grades

Light magnesium carbonate

Low bulk density grade for antacid formulations, dusting powders, cosmetics and food (E504) applications. Bulk density controlled grade-wise to your specification window.

Heavy magnesium carbonate

Higher bulk density grade suited to tableting and direct-compression excipient use, granulation and food applications where flow and compressibility matter.
