Fe2O3 and Fe3O4 of different combinations of red, brown, black, yellow, blue powder.
Melting point: 1565 ℃
Relative density (water = 1): 5.24
Solubility: insoluble in water, soluble in acid.
Molecular Weight: 160
Better dispersibility, hiding power, and colorability. UV has strong shielding. The human body does not absorb any side effects.
Uses:
1. The red-brown pigment powder as a low-level, industry, said iron oxide red, used for paint, printing ink, rubber and other industries.
2. Do Catalyst
3. Glass, precious stones, metal polishing agent
4. For the refining of pig iron, and CO reaction (H2 also) Fe2O3 3CO = 2Fe 3CO2 (high temperature) Fe2O3 3H2 = 2Fe 3H2O (high temperature)
5 is widely used in building materials (ceramics, color brick, tile, colored cement products) plastics, paint and other industries.
