In China, Kieserite is commonly referred to as 水镁矾 (shuǐ měi fán).
This name directly describes its composition:
● 水 (shuǐ) – water, referring to its water of crystallization (it’s a monohydrate).
● 镁 (měi) – magnesium.
● 矾 (fán) – a general term for vitriols or sulfate minerals.
So, Kieserite–“水镁矾” literally means “Magnesium Sulfate Monohydrate mineral,” that the exact chemical formula is MgSO₄·H₂O.

Meanwhile, in Chemical industry, Synthetic Magnesium Sulfate Monohydrate mineral has two kinds according to production process:
One is the Synthetic Kieserite which is incompletely water-soluble and widely used in fertilizer with excellent slowly nutrients release effect;
The other kind is completely water-soluble used as basic chemicals or mineral nutrients with awesome water-solubility.
