OVERVIEW

Ferrous Sulfate Heptahydrate

Product Introduction

[Properties] light blue-green crystals or particles, odorless, soluble in water, slightly soluble in alcohol, easy to oxidize in aqueous solution, corrosive, easy to weathering in dry air, easy to oxidize into basic ferric sulfate and turn yellow in wet air. The relative density is 1.897 g/cm3, the melting point is 64 ℃, when it is 56.6 ℃, it becomes tetrahydrate, when it is 65 ℃, it becomes monohydrate, when it is 300 ℃, it becomes anhydrous white powder, and when it is 480 ℃, it begins to decompose.

[Packaging] net weight of woven plastic bag is 25kg.

Product Applications

Ferrous Sulfate Heptahydrate is used for the production of high-end lithium battery cathode materials, and iron phosphate raw materials; Used as analytical reagent to analyze and determine platinum, selenium, nitrate, nitrite, etc; It is also used for photographic plate making, ferrite raw materials, iron intensifiers and fruit and vegetable colorants; In agriculture, it can be used as a pesticide and fertilizer, which can prevent and control wheat smut, apple and pear scab, and fruit decay. It is also a trace element fertilizer, which can accelerate the rejuvenation of rice and sugar beet, adjust the pH value of soil, supplement iron to plants, and remove moss and lichens from tree trunks; Raw materials for manufacturing magnetic iron oxide, iron oxide red and iron blue inorganic pigments, iron catalysts and high-end polymeric ferric sulfate; Used as local astringent and blood tonic in medicine; Food grade: used as nutritional supplement, such as iron enhancer, fruit and vegetable chromogenic agent; Feed grade ferrous sulfate is used as an iron supplement in feed processing.
