Calcium nitrate is a white crystalline solid that is highly soluble in water. It is tasteless and odorless, and chemically stable. It is composed of calcium ions (Ca2+) and nitrate ions (NO3-), serving as an important source of calcium and nitrogen. ◎ For Fertilizers It is commonly used for fertilizer applications, addressing calcium deficiencies in the soil. ◎ For Industrial Use Coolant: Calcium nitrate has the property of generating low temperatures when it reacts with water. Therefore, it may be used as a coolant in refrigeration and air conditioning systems. Dust Suppressant: Calcium nitrate has the effect of suppressing dust and binding fine particles in the air. It may be used for dust control in construction sites and mines.

Ferrous sulfate monohydrate is produced by centrifugally removing the crystallization water from the heptahydrate and then drying it. Compared to the heptahydrate, ferrous sulfate monohydrate is less prone to oxidation-reduction reactions in the air and has the characteristic of containing a large number of iron ions. ◎ Industrial Use It is used as a raw material for pigments and in wastewater treatment applications. In wastewater treatment, it functions as a reducing agent, coagulant, and precipitant. - As a reducing agent, it works to reduce hexavalent chromium to trivalent chromium in chromium-containing wastewater. - As a coagulant, it has a fast sedimentation rate, large and dense sludge particles, good removal effect for coloring agents, and the advantage of being inexpensive. - As a precipitant, it can form precipitates with sulfides and phosphates, allowing for the removal of these substances. ◎ Feed Use It is used as an animal feed additive, serving the role of iron supplementation. Iron is an essential nutrient for animal growth, being a crucial component of hemoglobin, myoglobin, cytochromes, and various oxidative enzymes. It also enhances the quality of livestock meat, giving it a more vibrant red color. ◎ Fertilizer Use It is used as a fertilizer to supply iron to plants.

◎About the Use of Fertilizers Iron (Fe), a trace element essential for plant growth, plays a central role in chlorophyll production and energy generation. A deficiency of iron adversely affects the life activities of plants, leading to serious issues such as leaf chlorosis and stunted growth. Among the solutions, ferrous sulfate is used as a reliable trace element fertilizer. Ferrous sulfate is water-soluble and is widely utilized as an essential trace element fertilizer in hydroponics. It is particularly effective in addressing iron deficiency in sandy and alkaline soils. In the agricultural sector, it is recognized as a fast-acting iron fertilizer. As for usage methods, spraying ferrous sulfate or applying it as a foliar spray are direct and effective ways to supply iron. Ferrous sulfate supports plant growth and health while efficiently promoting the uptake of iron from the soil. If the goal is to enhance productivity and quality, the use of ferrous sulfate is ideal. ◎About Industrial Applications Heptahydrate has many uses in wastewater treatment applications. It can be used as a coagulant, reducing agent, and precipitant to remove sulfides and phosphorus from wastewater.
