Product Introduction

Magnesium sulfate heptahydrate (molecular formula MgSO4-7H2O), also known as sulfur bitter, bitter salt, laxative salt, laxative salt, is white or colorless acicular or oblique columnar crystals, odorless, cool and slightly bitter, molecular weight: 246.47, specific gravity 1.68, easily soluble in water, slightly soluble in ethanol and glycerol, dissolved in the crystalline water in its own at 67.Chemicalbook5℃. Thermal decomposition, 70 ﹑ 80 ° C is the loss of four molecules of water of crystallization. Month 200 ℃ lost all the water of crystallization into anhydrous. In the air (dry) is easy to weathering for powder, when heated, gradually remove the water of crystallization into anhydrous magnesium sulfate, this product does not contain any toxic impurities. Magnesium sulfate heptahydrate is easier to weigh than anhydrous magnesium sulfate because it is not easy to dissolve, which is convenient for quantitative control in industry. Mainly used in fertilizer, tanning, printing and dyeing, catalyst, paper, Chemicalbook plastic, porcelain, pigment, matches, explosives and fireproof material manufacturing. Can be used for printing and dyeing thin cotton cloth, silk, as cotton silk weighting agent and cotton products filler; medicine as a laxative salt.

Agricultural use

Magnesium is the core element of chlorophyll, can strengthen the plant reduction process, improve disease resistance, it is essential for photosynthesis. Magnesium is the activator of many enzymes, which can promote the metabolism of carbohydrates, the synthesis of nucleic acids, and the conversion of phosphates. Magnesium sulfate is a very important fertilizer because it provides rich nutrients to crops. Magnesium helps in crop growth and high yield. Sulfur is the main component of proteins and enzymes that make up the body of plants, which promotes root growth and enhances metabolism and redox action in plants, thus promoting vigorous crop growth and increasing yields. Magnesium sulfate is a good fertilizer, which not only provides magnesium and sulfur, but also makes the soil loose and strong, and the root system of the plant is developed and fully absorbs the nutrients, so that the plant is more luxuriant. Magnesium and 15 other elements are considered to be the nutrients for plant growth and high yield, about plant nutrition Chemicalbook ingredients and fertilizers, traditional fertilizers contain nutrients (nitrogen, phosphorus, potassium) is obviously not enough to improve agricultural yields. Medium nutrients (calcium, magnesium, sulfur) and micronutrients (zinc, copper, iron, manganese, boron, molybdenum, and chlorine) are becoming less available in the soil, and deficiencies in these nutrients result in lower crop yields. Excessive extraction of magnesium from the soil has proved to be the main source of this widespread deficiency, and magnesium is an important ingredient in improving productivity and agricultural yields, and it must be replenished in a timely manner. It can be mixed with nitrogen, phosphorus and potassium into compound fertilizer or mixed fertilizer according to different needs, and can also be mixed with one or more kinds of primitive elements into various fertilizers and photosynthetic fertilizers respectively. After the actual fertilization of nine kinds of crops, such as rubber trees, fruit trees, tobacco, beans and vegetables, potatoes, cereals and so on, in the field of actual fertilization and comparison experiments, compound fertilizers containing magnesium can make the crops grow by 15-50% compared with compound fertilizers that do not contain magnesium.
