This technology increases 10% of the recovery rate in the platinum group metals associating with nickel and makes a whole improvement of China’s platinum metals industry. With the nickel carbonyl production line built, China will end long-term dependence of carbonyl nickel powder imports.
The principle of carbonyl metallurgy process is the use of transition metal and carbon monoxide g reaction of volatile carbonyl compounds of metals separation and extraction method, ordinary nickel-metal hydride battery nickel carbonyl, the main raw material powder is obtained using this technique. This technology can produce carbonyl nickel powder, nickel carbonyl balls, thousands of unique properties of high-quality products are widely used in military industry, metallurgy, chemicals, electronics, energy, aerospace, telecommunications, automotive and other specialty industries. Over the years, the technology has been mastered and a few countries have implemented technology blockade. The project, launched in 2000 R & D in 2003, built China’s first complete 500 tons / year production line and open up the process.

Nickel carbonyl (Ni (CO) 4) and carbonyl iron (F e (CO) 5) complex is a volatile liquid, they are using metal Ni and Fe, at a certain temperature, pressure, and synthesis reaction of CO gas. Carbonyl nickel (or iron) is very unstable at low temperature can easily dissociate into metal Ni (or Fe) and CO, by controlling the carbonyl compounds of pyrolysis temperature, time, etc., can be mass prepared from the nano to the micron level , even to the centimeter level, including zero-dimensional (nano-, micron particle material), one-dimensional (needle-like and filamentous material), two-dimensional (thin-film materials) and three-dimensional (pills, coated, gradient and hollow materials) materials the different shapes, different performance of the nickel (iron) products. With the current rapid progress of materials science and technology development to these shapes, strange performance nickel carbonyl (iron) products as raw materials, high performance can be developed in many high-tech products, they are in the electronics, chemicals, energy and defense areas copper powder(FCu) have a wide application prospect and great market demand.
