Transparent Yellow Iron Oxide Experiment

Hangzhou Fancheng Chemical Co.,Ltd | Updated: Dec 12, 2017

Excellent weather resistance of iron oxide is a common inorganic pigments.

According to the different hues, are divided into two types of iron oxide yellow and iron oxide red. For the former hydrated iron oxide, consisting of simple Fe2O3? H2O, which is Fe2O3. According to the size of particles, iron oxide pigments into clear and general categories. Transparent iron oxide called, refers to the kind of particle size <100nm. The size range is visible light diffraction conditions, so particles appear to be transparent. This test from the given references, please arrange to experiment and experimental design, independent operations. Specific requirements: provided by reagent conditions of selected instruments do not exceed the scope of time limit of 6 hours or less.
