China Jilin Makes Carbonyl Iron Powder, Nickel Powder And Molybdenum As Industry Focus
The Carbonyl facility at Jilin was designed, engineered and constructed by CVMR Corporation. CVMR is a shareholder in the Jilin facility and has been producing nickel and iron powders and variety of nano-powders over the past 15 years. Despite the downturn in the commodities market, the demand for various metal powders remains quite strong and in certain cases actually increasing. The latest China Jilin metallurgical industry development plan proposed the development priorities and layout. … Continue reading

Carbonyl Nickel Powder Has A Potential Market In China
Production process of carbonyl nickel is not a new technology and has study history for 100 years. China’s research time is about tens of years. Refining of nickel carbonyl is a simple process with low energy consumption and high extraction rate. It also conducive to non-precious metal waste environmental enrichment process and can produce high-purity nickel balls, metal powder, alloy powder, powder coated, foam nickel and nano nickel powder. But within a long time, … Continue reading

Carbonyl Iron vs. Ferrous Iron
Carbonyl Iron Less Toxic and Better Tolerated than Ferrous Iron Slower to Absorb With ferrous iron, generally all iron is available for absorption. However, with carbonyl iron, only a small percentage is available for absorption.1,2 The rate at which your body absorbs carbonyl iron depends on the production of gastric acid (which is required to make carbonyl iron soluble), and the balance between the iron being dissolved and absorbed by your intestines. This means … Continue reading

Forms of Iron
Iron comes in two forms: heme iron (from meat and animal products) and non-heme iron (from other sources like vegetables and iron supplements). Non-heme iron used in iron supplements can appear in 3 forms: Ferric iron (Fe3+) — This type of iron is less soluble than ferrous iron in an environment when pH is greater than 3. It has to be converted to ferrous iron (Fe2+) so that it can be dissolved and absorbed … Continue reading
