Product Description

Magnesium Sulfate (or magnesium sulphate, Epsom salt ,Bitter salt ) is a chemical compound containing magnesium ,sulfur and oxygen,with the formula Mgso4. In its hydrated form ,the PH is 6.0(5.5-6.5).It is often encountered as the heptahydrate ,Mgso4·7H2O, commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent .Since the anhydrous form is hygroscopic (readily absorbs water from the air )and is therefore difficult to weigh accurately, the hydrate is often prefered when reparing solutions ,for example ,in medical preparations ,Epsom salt has been traditionally used as a component of bath salts .

Product Name Magnesium Sulphate MgSO4.7H2O
CAS NO 10034-99-8
HS Code 28332100
EINECS NO 231-298-2
Formular MgSO4.7H2O

In agriculture and gardening ,magnesium sulfate is used to correct magnesium derficiency in soil ,since magnesium is an essential element in the chlorophyll molecule. It is the commonly applied to potted plants ,or to magnesium-hungry crops ,such as potatoes ,roses ,tomatos ,peppers amd cannbis. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic line )is its high solubility.

Appliocations of Magnesium sulphate

Magnesium is the center element of chlorophyll,photosynthes can't go on without it. It is the activating agent of many enzymes,such as it can promote the metabolism of carohydrates,nucleic acid synthesis,the conversion of phosphate,etc.

1.Magnesium sulphate for agriculture
Sulfur and magnesium can provide rich nutrients for crops that it contributes to crop growth and increase the output, it also helps to loosen the soil and improve soil quality.
The symptoms of lacking of "sulfur"and"magnesium":
1) It lead to exhaustion and death if it's serious lacked;
2) The leaves became smaller and its edge will became dry shrinkage.
3) Susceptible to bacterial infections in premature defoliation

It can be used in printing and dyeing, Industry,monosodium glutamate and yeast fermentation and as accessory ingredient for ABS and PVC resin

3.Magnesium sulphate for stock raising
Magnesium is usually Fertilization among the early spring and the end of the year, until the grass can provide adequate magnesium ,it can also added in the feed and drinking water to meet growing demand of dairy cow's sebum, in order to improve the quality and quantity of milk cows.

4.Magnesium sulphate which contains a small amount of crystal water or non-crystalline water can be used for organic synthesis and the desiccant and dehydration agent of feed and Fertilizer.

Synthetic Kieserite:
1. High Magnesium supplement to promote photosynthesis of plant.
2. Widely used in fruit, vegetable and especially for palm oil plantation.
3. Good filler to be used as material of compound NPK.
4. The granular is main material for blending fertilizer.
