Magnesium Sulphate Anhydrous
Grade Standard
Agriculture, Electron, Food Grade
Product Description
Magnesium sulfate has various contents and classifications, and can be classified into industrial grade agricultural grade according to its use; According to the state, it can be divided into magnesium sulfate heptahydrate, magnesium sulfate monohydrate, anhydrous magnesium sulfate, etc; Generally, there are various forms such as crystal particles, powder, spherical particles, etc. Magnesium sulfate is unstable in the air. Magnesium sulfate heptahydrate is prone to dehydration in the air, while anhydrous magnesium sulfate is prone to water absorption.
