Gelemash 313 iron oxide

Gelemash 313 iron oxide is a yellow powder, non-toxic, very proper color resistance, excellent optical resistance and high coating power, in a group of mineral pigments, with Fe₂O₃.H₂O chemical formula that usually made of a stone named Limonite.

What is Gelemash 313 Iron oxide?

This matter with needle-shaped geometric structure, it has trivalent iron atoms and also water molecule, in its structure, because of that it is famous as three hydrated Iron oxide.

Gelemash 313 advantages and properties

In terms of color this matter is very similar to chrome yellow mineral pigment, it has, very good chemical stability, pure and bright color, very good atmosphere resistance and high optical resistance.

Gelemash 313, between 150-200 ^℃ temperature, lose the water in formula, and will become di- hydrated. In this case, its color gradually tends to red, if higher temperature is necessary, its obligatory to use cover modification on pigment surface.

Gelemash 313 iron oxide applications

According to properties and features that is mentioned above, this matter is used at different part of industry and producing different products, for example because of the weakness in temperature tolerant and also as colorant in producing dye, rubber, ink, paper, plastic, agricultural fertilizer and ethylene vinyl acetate (EVA), because of the needle-shaped structure and high absorption of water, is used to produce building materials, concrete, cement and etc

Iron oxide use and maintenance conditions

This material is categorized as non-toxic materials, and any danger of using that isn’t reported yet. Nevertheless, while prolonged contact, is recommended to use gloves, mask, hat, glasses and safety clothes.
