micronsize carbonyl iron powder

The carbonyl iron powder is used to react with iron in high temperature and high pressure, producing 5 carbonyl iron oil, and then being separated by low pressure to get the product.It can be shipped by annealing and oxidation treatment.When the temperature is 200 ℃, 200 bar under the condition of carbonyl synthesis reaction is as follows
Fe + 5CO = Fe (CO) 5
Carbonyl iron at 300 ℃, 1 bar under the condition of decomposition for Fe and CO
Fe(CO)5= Fe+5CO
Performance: Carbonyl Iron Powder has the features of spheroider particles, wee particle size and high purity. The dust core made of it is excellent magnetic material. It is a kind of gray or silver gray hyperfine powder in irregular shape.
