GRANULES OF NITRIC ACID-BASED SALT AND AGGREGATE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide nitric acid-based salt granules which are each hard to roll by themselves when they are transported and hard to crumble when they are heaped into an aggregate. SOLUTION: In granules obtained by forming a compound containing a nitrate or a nitrite into a granular form, a projection part 3 projecting in a handguard form is formed at the outer peripheral face in the radial direction of each granule main body 2.
