Use of iron oxide
Iron oxide is a kind of inorganic substance chemical formula Fe2O3. Red or dark red amorphous powder. Relative density 5~5.25, melting point 1565℃ (simultaneous decomposition). Hydrochloric acid and sulfuric acid are insoluble in water and slightly soluble in nitric acid. Covering and coloring power is very strong, with no oil or water permeability. Stable in the atmosphere and sunlight, resistant to dirty gas, high temperature, and alkali resistance. The dry process products of this product are coarse and stiff, suitable for magnetic materials, polishing, and grinding materials. Wet-process products have fine crystalline particles, soft, and are ideal for the coating and ink industry. Magnetic materials Because of its special superparamagnetism, magnetic iron oxide particles have broad application prospects in giant magnetoresistance, magnetic liquid and magnetic recording, soft magnetic, permanent magnetic, magnetic cooling, oversized magnetoimpedance materials, magneto-optical devices, magnetic detectors, and so on. Videotape usually uses needle-like iron or peroxide magnetic ultrafine particles, and nano iron oxide is a new magnetic recording material. Soft magnetic ferrites have been widely used in radio communication, radio and television, automatic control, space navigation, radar navigation, measuring instruments, computers, printing, household appliances, and biomedical fields. Pigment field iron oxide as a pigment is widely used in high-grade automotive coatings, architectural coatings, anticorrosive coatings, and powder coatings, and it is a better environmental protection coating and the world's annual consumption of iron oxide pigments of more than 1 million t, second only to titanium dioxide, inorganic pigments second. The use of iron oxide as a pigment not only maintains the general inorganic pigment's good heat resistance, weather resistance, and UV absorption advantages but also can be well dispersed in the oil carrier, with its modulation of paint or ink having satisfactory transparency. Iron oxide coating with semiconductor properties can play an electrostatic shielding role because of its high conductive properties.
