| abstract |
The present invention provides magnesium oxide granules capable of improving the dissolution and production defects in tablets. Adjusted the content of B (boron) to 0.05% by weight or less, the content of Ca (calcium) to 0.03 to 1.8% by weight, and the net content (Assay) to 95 to 99% in magnesium oxide granules Do. Since such magnesium oxide granules are high in purity, they can be suitably used particularly for food, medicine, cosmetics and the like. |
